Re: Reading bytes from an audio file

Brian,

How big is the file? The byte count returned from AudioFileGetProperty() is a SInt64 value but you have to pass a UInt32 * for the size of your buffer for AudioFIleReadBytes(). You wouldn't be able to read all the bytes in one pass if the byte count is larger than a UInt32 value. Sure you aren't passing 0 bytes for your size?

Hello

I am trying to load the audio bytes from a WAV file.

I am doing this by first reading the size property of the audio file using the function AudioFileGetProperty().

Using this size I try to read the audio bytes using the function AudioFileReadBytes, into an array of the same size, which is allocated through malloc(sizeof(char) * theAudioDataSize).

This keeps giving an kAudioFileUnspecifiedError! If I just try to read in 1024 bytes there is no error!

Anybody out there who knows if and what I am doing wrong?

The functions and error codes are all declared in the header file AudioFile.h.

Thanks

Brian
