wavload

A small example that demonstrates how to externally load .wav files.

Works on GameMaker: Studio 1.4 and above, importing this project into newer GM versions will work.

Usage

audio_load_wav(fname) loads file fname and returns the wav array.
audio_load_wav_buffer(buffer,[offset]) loads sound from buffer starting from offset and returns the wav array, if no offset was specified, offset 0 is assumed.
audio_free_wav(arr) properly frees the wav sound loaded by audio_load_wav* functions, the array, buffer, and the sound must NOT be used after you called this function.
audio_exists_wav(snd) checks that the wav array (and both the buffer and the sound) is valid.
WAV Array:
- [0] - GM:S Audio Index, use in audio_* functions except audio_exists and audio_destroy_stream.
- [1] - Raw Sound Data Buffer Index, DO NOT FREE this buffer, it's only there just so audio_free_wav can free it.

Only PCM 16-bit or 8-bit files will work, as that's the only two formats GM supports.
Only Stereo or Mono, for the same reason, GM also supports some weird "3D Audio (5.1)" format, if the channel number is invalid the script will assume it's that weird 3D Audio, expect issues though.
Files exported from Adobe Audition maybe won't work, they add some external data to the .wav and I'm too lazy to implement that (same with ffmpeg?). Please just use Audacity, it's perfect.
