Hi, you may or may not find this useful.

SoundWriter is an Actionscript 3 library that allows you to create Sound objects from your own audio data. That is, you write into an audio buffer (ByteArray) with whatever audio data you want, process it through SoundWriter, and get a Sound object out of it. This is something which isn't provided by Flash 9 directly, but is achievable with a little trickery.

How this library may be of use to you:
Synthesising your own sound effects ahead of time
Creating audio from supplied data
Loading WAV files from binary resources (not possible if you don't have Flash CS3)
Creating music from other sound files not supported by Flash – e.g., a MOD file renderer allowing your game to incorporate music into your game without upping the file size with a 5MB MP3

Looks great!

Could you explain though . Why is loading WAV files from binary resources not possible without Flash CS3?

I don't know. You can embed MP3s like this:


[Embed(source="sound.mp3")]
private static const soundClass:Class;

but it's not supported for WAV. Crazy, huh? It's especially annoying as MP3 files have silence added to the beginning of them by the encoders, so if you use them as sound effects you find that there's a slight latency before you actually hear anything.

Ah okay. But you can import wavs into Flash IDE yeh?

Yeah. But a lot of us don't have/use/like it.

Anyway, it's not the primary usage for this sound library :-)

Hi

Wayne. The link in your blog doesnt seem to work. Am i right if assuming that your library can create an instance of Sound class from a bytearray?

always great to see sound advancements in AS3!

Andre Michelle and Joa Ebert have also written a module player in as3 ...
