A Brief Information Guide About Audio Codecs


Audio codecs are defined as software applications of hardware devices (with the same kind of software) that can compress audio files and then decompress them. In fact, the codecs used for compression and decompression work with opposite principles, but they are quite similar to each other in the manner of their working


The formats used by audio formats are any applicable digital audio formats that are commonly used. For transmission over the Internet, codecs can also compress and convert files into streaming audio formats.

The word 'codec' is derived from coding-decoding, which is what a codec does. It first codes the digital data into a small compressed form and then plays back the data by reconverting it into the original form.

Audio Codecs – How do they work?

Audio codecs work with the principle of audio compression. This is a process of reducing the size of an audio file so that it is covered within as few bits of data as possible. The idea is to remove all unnecessary sound bits and bundle them into a smaller format so that they are compressed. When the file needs to be played back, a decoding system is put into play which can expand the files again so that they can be played.

Lossless and Lossy Audio Codecs

There are two types of compression that audio codecs can perform. Based on that, they are called as lossless and lossy audio codecs.

Lossless audio codecs retain a copy of the original audio files before converting them, so that any kind of qualitative or quantitative loss becomes reversible. However, this also increases the size of the file even after compression. It is difficult to have a lossless audio codec that can compress an audio file below 50 to 60% of its original size.

Lossy audio codecs are those that do not retain any previous information. They compress the audio to the smallest size possible and transmit them where they are decoded to a playable size. However, there is a danger of loss of data because of the fact that there is no backup created. The brighter side of this is that lossy audio compressed files are substantially smaller in size. These can easily compress the files to 5 to 20% of their original size.

Today, most audio codecs available in the market are of the lossy type. Though they will cause a deterioration of the quality of the file, they are good for online transmission and even storing on discs. For that reason, people prefer lossy audio codecs over the lossless ones.

Audio Codecs – The Tradeoff

There is always a compromise involved when audio codecs are used. It is not possible to predict in advance how these files will be compressed and whether they will play at good quality upon being decompressed or not. This is especially because most codecs used today are lossless. Though this becomes ideal for sending digitally compressed audio files over the Internet, they also mar the original quality of the recording. Hence, these audio codecs are used only sparingly and only in areas that really require them.

After Testing with QTP or LoadRunner, Manage your tests with HP- Quality Center

Introduction to Quality Center:
Quality Center is a versatile tool brought out by HP, for managing the complete application testing process. When we say the management of the application testing process; it includes the process of customizing the test project, defining the releases, specifying requirements, planning of tests, execution of tests, tracking of defects, issuing of

alerts on changes, and finally analyzing the results.
It should not be misunderstood as a tool for testing the functionality of the applications. Not being a testing tool as such, it does not use any scripting language. Or in other words, we can’t write or execute any script in Quality Center.

Quality center can be used to write functions in such way that enables us to open the Test script in a performance-testing tool like QuickTest Professional and when desired, we can save it in Quality center.

Key Features of Quality Center:

Following features render Quality Center as a most versatile test management tool.

1) Maintains a Common Repository
2) Offers Automatic Traceability Matrix
3) Excellent Bug Tracking facility
4) Offers Automatic Reports and Graphs generator

How to use the Quality Center:

Broadly we can bifurcate our process of using Quality Center into following four Modules or phases.

1) Requirements Module
2) Test Planning Module
3) Test Execution Module
4) Defects Management Module

1) Requirements Module:
It comprises of clear identification & validation of all functional and performance requirements expected to be tested in our application. These requirements, once described with ample clarity provide the test team a solid foundation on which the entire testing process is based. The process involves listing out the entire Primary or Main Requirements (Say MR1, MR2, Mr3 etc.) along-with sub-requirements or Child Requirements (Say CR1, CR2, CR3 etc.).

For the entire Requirement identified above, a Test is planned. For Manual Testing, the term “Test” refers to creation of a Test Case, while for an Automated Testing, the term “Test” refers to creation of a Test Script.

Requirements Module of Quality Center offers facility of defining two types of Requirements Like
1) Defining New Requirement
2) Defining New Child Requirement

The Requirement module displays the information through following fields:

1) Author: Displays the user name of the person who created the requirement. By default, this is the login user name.

2) Comments: Displays the comments about the requirement.

3) Creation Date: Means the date on which the requirement was created. By default, the creation date is set to the current database server date.

4) Creation Time: Means the time at which the requirement was created. By default, the creation time is set to the current database server time.

5) Description: A description of the requirement.

6) Direct Cover Status: The current status of the requirement. Various types of requirement status can be like Not Covered, Failed, Not Completed, Passed, No Run, N/A, Not direct cover etc. By default, the status is Not Covered.

7) Modified: Indicates the date the requirement was last changed.

8) Name: The requirement name.

9) Old Type: The type of obsolete requirement.

10) Priority: The priority of the requirement, ranging from low priority (level 1) to urgent priority (level 5).

11) Product: The component of the application on which the requirement is based.

2) Test Plan Module:
It comprises of the prime activity i.e. creation of clear and concise Test Plans in line with the requirements formulated in the Requirements Phase. A nicely prepared test plan enables us to assess the quality of our application at any point in the testing process. Before proceeding ahead, with the help of Traceability Matrix, it is ensured that all the requirements have been duly addressed in the Test Plans.

Addressing all the requirements, various Test Plans are created either manually or automatically.

The process involves following key steps:

a) Creation of a folder
b) Creation of an empty test.
c) Launching of the available functional testing tool like HP – Quickest Professional etc.
d) Creation of the Test Scripts.
e) Saving the Test Script in the empty script file already created.
f) Repetition of above steps till creation of test plans covering all the test requirements gets completed.

For maintaining an automatic traceability, it is essential that the tests in the test plan meet our original requirements. Hence links are added to keep track of the relationship between our requirements and the tests.

A test can cover more than one requirement, and a requirement can be covered by more than one test, hence linking can be done accordingly. We can link requirements and tests to the defects. This can help you ensure compliance with our testing needs throughout the testing. If a requirement changes, we can immediately identify which tests and defects are affected, and who is responsible for it.

3) Test Lab Module:
As the application undergoes changes, the manual and automated tests are run in our project with a view to identify the areas of defects and make judgement on the product quality.

The flow of this module is as under

a) Creation of Test Sets: A test set is a group of tests in a Quality Center project designed for achieving some particular testing objectives. The process begins with the identification of all the end-to-end scenarios, followed by creation of individual test Sets for every such end-to-end scenario.

After creating the test sets, tests set folders are created and assigned to development and QA cycles based on the project timeline.

b) Scheduling Test Runs: Quality Center enables us to control the execution of tests in a test set. We can set conditions, and schedule the date and time for executing our tests.

We can define the sequence in which to execute the tests. For example, we can define to run “test2” only when “test1” has finished, and run “test3” only if “test1” has passed.

c) Running of the Tests: After defining the test sets, we are ready to execute the tests. We can select all the tests in a test set, or some specific tests. Our selection can include both automated and manual tests. We can run either a single test or all the tests in the test set.

# Running Tests Manually: When we run a test manually, we execute the test steps defined by us during test planning stage. We declare a step either pass or fail according to the fact whether the actual results of the application matched the expected output or not.

# Running Tests Automatically: While running an automated test, the selected testing tool opens automatically, runs the test, and exports the test results to Quality Center. When we run a manual test, an e-mail is automatically sent to the specific tester, prompting to run the manual test.

d) Analyzing Test Results: After a test run, the test results are analyzed to identify the failed steps and to determine whether a defect has been detected in our application, or if the expected results of our test need to be updated. In case a defect gets detected, we can create a new defect and link it to the test run, or link an already-existing defect with the test run.

After the test execution gets finished the results can be analyzed through the Functional Testing Tool itself (like QuickTest Professional). The identified defects can be directly posted through the QuickTest Professional itself, alternatively the Defects Module of HP Quality Center can be used.

4) Defects Module:
This module is like a Bug Tracking Tool and helps us in reporting the design flaws in our application. This provides all the facilities to manage the defects like adding of defects, changing the status of defects and analyzing the defects etc.

a) Adding Defects: When a defect is found in the application, it is submitted to the Quality Center project. The project stores the defect information and it can be accessed by the authorized users only say like the members of the development, quality assurance, and support teams. This new defect can be associated with the cycle and release in which it was detected. The new defect can be associated with the test we ran, for future reference

b) Reviewing New Defects: During this stage we decide as to which defects needs to be fixed. The project manager usually performs this task. Here we change the status of a new defect to “Open”, and assign it to the concerned member of the development team for fixing.

c) Repairing Open Defects: This involves identifying the cause of the defects, modifying and rebuilding the application. Application developers perform such activities. When a defect is repaired, we assign it the status “Fixed”.

d) Testing a New Application Build: Involves running of the tests on the new or 2nd build of the application. If the defect does not come up again, we assign it the status “Closed”. However If the defect is detected again, we assign it the status “Reopen”, and it is returned to the previous stage. The quality assurance manager or project manager usually performs this task. Doing testing on 2nd build on wards is called Re-Testing or Regression testing.
Repeated testing from the Test Lab Module to Defects Module is carried out till all the defects get fixed.

e) Analyzing Defect Data: View data from defect reports to see how many defects were resolved, and how many still remain open.

Interconnectivity of Quality Center & QuickTest Professional (QTP):

Applications can be tested using following two ways:

1) Through QuickTest Professional: By defining path for Quality Center while being in QuickTest Professional.

2) Through Quality Center: By launching QuickTest Professional while being in Quality Center.

Effective EMR Software For Single and Small Medical Practices

ingle and small medical practices need all the help they can get when it comes to managing the practice. Employing more staff won't solve the problem of operational efficiency and effectiveness as the practice continues to grow. Doctors
must learn to turn to technology, and harness the benefits of powerful software to help run their practices.

And that is exactly what thousands of small medical practices have done. By utilizing EMR (Electronic Medical Records) or

PM (Practice Management) software, small practices have managed to reduce costs, and increase their profit margins. Software has allowed the practices to grow and scale, while keeping everything ship shape. This is, by no means, an easy feat. Consider the activities that is happening in a medical practice during a normal working day.

Staff has to work with an increasing number of patient records. Small practices used to manage such records manually, which is doable while the practice is still small. But as the number of patients increases, it can be a nightmare to store and retrieve records.

The practice also depends very much on patient appointments for revenues. That means patients must turn up for medical appointments before any revenue is made. Often, appointments are being missed for various reasons. Patients may forget about a scheduled appointment that is 6 months ahead. Without proper management software, there is no way staff can remind the patients to come for appointments.

Then there is the issue of expected revenues and realized revenues. To make business related decisions for the practice, doctors used to rely on unreliable financial information. A lot of decisions are made based on guesswork. In other words, they perceive that the business is having a healthy cash flow. But expected revenues is very different from actual revenues. Bill collection poses a constant problem to many medical practices. Patients forget to pay bills, claims are not filed on time, etc. This affects the cash flow of the practice.

To manage the practice properly, it is wise to invest in a comprehensive suite of EMR software. Such software can help schedule appointments, keep patient records organized, help with bill collections, and increase the overall efficiency of the entire business.

So far, this is just from the perspective of the practice. What about the perspective of the patient?

Patients will find that the medical practice is more professionally, and they will appreciate staff members calling them up and reminding them of upcoming appointments. If there is a need to go for a medical appointment, it is in their best interest to show up for the appointments. Otherwise, they may fail to follow through on the healing plan that the doctor has mapped out for him or her. In other words, EMR software helps the practice offer higher quality medical practices. Even if a practice has no intention to grow as a business, patients have learned to expect better medical care with the help of modern technology.

For the above reasons, many medical practices have chosen to upgrade the applications that they are currently using

Medical Appointment Scheduling - Affordable and Comprehensive Software


MAS, or Medical Appointment Scheduling software, helps single and small medical practices manage patient appointments. There are many benefits when it comes to utilizing technology. For instance, the practice enjoys increased productivity, higher customer loyalty, and increased revenues. In this case, it is not only the practice that gets to enjoy all the benefits. The patients get better medical care too. It's a win-win situation.

Often, there are

several factors that cause doctors to be resistant to installing appointment scheduling software. Some worry that the licensing fees can be too expensive. For sure, this is an undue worry because there are always various licensing options available, even for the smallest medical practice. These options are available to suit the different needs of different practices. They also allow practices to upgrade their licensing according to the growth of the practice. Hence, there is no need to worry about the fees. When the practice is small, fees are highly affordable.

Here is an example. Let's say your organization has only 4 people. At any one time, the maximum number of people accessing the software is 4. That means you only have to pay for 4 licenses. It does not matter if you have 10 or 20 computers. You can install the software in all your computers with only 4 licenses. This leads to lower licensing fees.

Not only are the fees affordable, the features are also quite comprehensive. For example, you can easily synchronize your appointment scheduling software with your Quickbooks(R) software so that data remains consistent across the board. Also, the software has HIPAA security, which means that you don't have to worry about compliance issues.

Some doctors do not believe in using technology. They still have the mindset that there is no need for such software. They can keep track of their appointments manually. However, the manual method has been proven to be highly inefficient, and it is common sense that the practice cannot scale beyond a certain limit. Without the help of technology, the practice will hit its ceiling very soon. When that happens, it is very difficult to help more patients - the practice is stuck.

Sometimes, resistance to change may be caused by fear of technology. The worry is that staff has to be tech savvy, and doctors have to be kept on their toes at all times due to technological changes. But this belief is flawed because software publishers usually take care of everything - from product development to providing regular product upgrades. There is no need for doctors to worry about these issues. Leave them to the professionals. So far, it appears that they are doing an excellent job. Scheduling software in the market place today are designed to be easy to use, customizable, flexible, and stable.

In addition, support is just round the corner. All you have to do, is to make a quick phone call and a trial version of the software will be setup to work with your existing software. You can experience for yourself, first hand, the ease and convenience of using appointment scheduling software.
