lab 82, again


lab 82, again - txt2iaf


After thinking the matter a little, I finally wrote the txt2iaf app. This allows to use any text file, with one or two columns of data, to be converted to an iaf file that can be played using auplay(1). Now, my sound analysis goes something like this:

1. Record something using a microphone. For now, I only record stuff using some app in Windows (Sound Recorder) or Linux (arecord(1)). This is because Inferno has some issues when trying to record something from /dev/audio: an annoying tick every so often that wrecks my sound analysis intentions. Maybe, I can help to fix this problem, probably related with buffering.

2. Convert the wav file obtained to an iaf file, using wav2iaf(1).

3. Get the data from the iaf file to a text format, using iaf2txt(?).

4. Read data from the text file using any data analysis package.

5. Do whatever you want to with the data.

6. If you wish or need to, output the data in a text file.

7. Using txt2iaf(?), create an iaf file using the data in the text file. Enjoy your new song using auplay(1) ;-)

8. If you want to, convert your iaf file to a wav file using iaf2wav(?).

I also fixed some ugly code in iaf2txt(?) and iaf2wav(?) (really ugly, indeed). Please, update.
