I use with the [shell] (to get tags under Ubuntu) : totem-video-indexer audio_file_path
For example : $ totem-video-indexer '/home/jack/Musique/[1999] SYR4 - Goodbye 20th century disc 1/Disc 1/1-01 - edges.mp3' TOTEM_INFO_TITLE=Edges TOTEM_INFO_ARTIST=Sonic Youth TOTEM_INFO_YEAR=1999 TOTEM_INFO_ALBUM=SYR4: Goodbye Twentieth Century [Disc 1] TOTEM_INFO_DURATION=963 TOTEM_INFO_TRACK_NUMBER=1 TOTEM_INFO_HAS_VIDEO=False TOTEM_INFO_HAS_AUDIO=True TOTEM_INFO_AUDIO_BITRATE=192 TOTEM_INFO_AUDIO_CODEC=MPEG 1 Audio, Layer 3 (MP3) TOTEM_INFO_AUDIO_SAMPLE_RATE=44100 TOTEM_INFO_AUDIO_CHANNELS=Stéréo
With a grep and [symbol] + [s2l =] + [unpack s s], you should get what you are looking for (i am not sure that it works with all files). ++

Hi all
I am looking for a way to get information about WAV files in Pd, specifically the number of channels and the number of frames. I know [wavinfo], but it does not seem to work on windows ("error: could not read WAV-header" with any file I could find) and on linux it seems to read only a subset of WAV formats. It does not read from widely used broadcast format WAV files. The target platform is windows AND linux anyway in this case, so I need a portable solution.
The most troubling fact is, that some Pd-vanilla classes ([soundfiler], [readsf~]) actually do retrieve the information I need, they read both, the number of frames and the number of channels correctly, with all pcm encoded wav files I tried, but - what a pity - they don't expose this information to the patch level.
Hopefully I am overseeing the obvious here. Hints are very welcome.
