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!

sound sample rate resampling

Asked by florinsuciu in Java Programming Language

Tags: java, resample, sound

Hi!
I have needed to do in Java an resampling from an sound (WAV or MP3) that have sample rate equal with 32KHz into a sound with 48KHz.
I have the array of sound samples, which will be filtered.
I have applied the bottom algorithm but I have obtained a sound with distortions (the resulted sound is played faster than the original sound.)
Algorithm: if we have a 32000hz rate in order to convert it to 48000hz we'll add between 2 sound samples a new sample equal to the first one. As input sound samples array will be X Y X Y X Y X Y and as output will be XXY XXY XXY XXY, so that the output array we'll have the size 1.5 of the input sound array.

Any suggestions, algorithms, sample code or URL links will be appreciated.
Thank you,
Florin
