The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

Convert Wave Sample Rate

Asked by nacker2000 in Delphi Programming

Tags: convert, rate, sample, wave

Hi all

I am sampling audio from a number of sources mainly at 44100 16bit stereo but some sources are 48000 16bit stereo and I need to convert these sources to 44100.

I have the actual raw audio data available to me in memory so what I am looking for is some code (a function or procedure) which I can pass the audio data pointer and a target sample rate and have it returned in the correct format on-the-fly.

I can do this through the ACM but its not ideal and relies on opening, closing and managing the ACM. I would much prefere it in code.

I have searched the internet on some way to do this or even an explanation of how it could be done but I can't find anything. It's either really easy to do and I am overthinking it or it's just not very well documented.

Any help is appreciated.

Thanks.
