[squeak-dev] how to extract the audio from .pr?

Hi guys

I'm a newbie using squeak,
I'm having some troubles, perhaps you could help me :)

I would like to extract the audio files from a squeak Open Learning
Exchange Nepal activity (.pr file).

In the past I exported some images from the .pr file using the
"export" button. In the "sound library" I didn't find a way to do
that. could you please give me a hand?

thanks guys

there is no easy way to export these sounds, that I know of.
If you look at AbstractSound in category file i/o you will find methods
to file the sounds out.

Let me know if you need more help

cheers,

AFAIK, there are no ready-made methods to export sound in any compressed
formats. The sound library in SampledSound class stores sounds as raw 8-
bit/16-bit samples. The class has methods to read WAV and AIFF files but no
corresponding write methods :-(. You could write out raw samples from the
sound clip in the library and then use sound conversion utilities on the host
to convert samples to WAV, mp3 etc.

Excellent!, I can convert it, the part that I didn't know was how to extract the audio. I'll try it using SampledSound class. Thanks.

SampledSound is a subclass of AbstractSound, so you get all its
#store... methods, such as #storeWAVOnFileNamed: or #storeAIFFOnFileNamed:
