How can I play a sound based on waveform data that my .Net program is generating from user input and mathematical functions? By "waveform data" I am mean SPL values in a fixed interval time-series (probably 44.1 kHz). I presume that this requires some...

You will need.
Per comment: Yes, I know.
Maybe something like this will help
Check out this thread on loading up a DirectSound buffer with arbitrary data and playing it.
Fill with your generate data.

I have a waveform 64 samples long. If the sampling rate is 44100 hz, how can I play(loop) this waveform so that it plays arbitrary frequencies?
frequency = samplerate / waveform duration in samples
Therefore the frequency should be 689hz(44100/64). If...

Loss (maybe you should have your wave data longer than 64 samples) but cannot possibly change:
frequency = samplerate / waveform duration in samples
Um, if by "waveform duration" you mean the period of a wave, then yes.

N is a count of some.
Let N be the cycle length (1 / frequency).
That file contains your waveform.
Repeat.
Logical 0 for 1 seconds worth of data; then emits logical 65535 for one second worth of data.

I was wondering if anyone has any suggestions on how to go about rendering a waveform of an audio file. I wold like to enable the user to set an in and out point of an audio track and I need to have a waveform so you can see where to put the points.

An audio waveform, you will want to do some sort of data reduction on the original data, because there is usually more data available in an audio file than pixels on the screen.

I'm about to start a project that will record and edit audio files, and I'm looking for a good library (preferably Ruby, but will consider anything other than Java or .NET) for on-the-fly visualization of waveforms.
Does anybody know where I should start...

The only viable option is a BLOB for that kind of a dataset .
Option 3 is the way of points per waveform.
To a lesser extent, the same objection would apply to option 2 .

Hi all,
This question has been in my mind for a few years and I never actually found the answer for this.
What I would like to do is extract the actual waveform/PCM of an MP3 file, so that I can play it using the soundcard (of course).
Ideally I would...

On the Mac, I would to accomplish is playing with audio data, then probably decoding an MP3 to uncompressed PCM using any.
They should both have the ability to decode mp3 files into the raw waveform.
