Unable to play a .wav file using the sample... about novocaine HOT 5 CLOSED

Wav files aren't compressed, so it doesn't require all the fancy readers that I have implemented in the sample. You can just skip the header information, and then start reading binary values. I've never done that, because it's not space or power efficient on the iPhone to do so (reading from disk is more expensive than running decompression on the ARM chip).
I'd recommend converting to m4a and proceeding from there.

Hi Alex, would you know why .wav files wont play on this example? Which parameters do I need to change/tweak to make it play? The wav file is sample rate: 11025, bits per sample: 8, channels: 1

Thanks Alex I have already written the new code to process the WAC file but it sounds cartoonish as if it is being played too fast. What do I need to change in nova canine or in the wav processing to match the playback rates to fix the cartoonish sound?

That sounds like you're playing a mono file out to stereo. Make sure that if you have a mono audio recording, you write it correctly into the stereo output buffer.

I c. Would u happen to have any samples laying around to copy from mono to nocaine's output block by any chance?

I ended up reading this thread because I need to read uncompressed data into a unit test fixture. The sounds are actually encoded data, so I really don't want to apply lossy compression. Also this is test code, so the performance on the iPhone isn't relevant. I just want to load data as if it was a buffer from setInputData, so I can test how it is handled.
I'm not demanding anyone adds support for that, just pointing out that it is a valid use case!
