Re: [PD] Recording audio to mp3 using LAME or ffmpeg ?
Seems like I forgot to respond to this thread I started. Thank you all for the tips, I think I'll go for oggwrite~. Cheers, Pierre. 2012/10/5 Hans-Christoph Steiner h...@at.or.at I think there is mp3write~ in 'unauthorized' lib but I've never used it. There is the pdogg lib, which has oggwrite~. .hc On 10/05/2012 06:55 AM, Pierre Massat wrote: Dear List, How would you go about recording the audio output of a Pd patch directly to mp3 (or any other compressed format actually), without using the object from the Unauthorized library ?

[PD] Recording audio to mp3 using LAME or ffmpeg ?
Dear List, How would you go about recording the audio output of a Pd patch directly to mp3 (or any other compressed format actually), without using the object from the Unauthorized library ? Would it be feasible to use the [shell] object with a script using ffmpeg or LAME ?

I don't really know whether there would be serious timing uses, who to use those for recording a stream instead of a file, how to send Pd's audio out... use jack and ecasound? gstreamer objects for pd? hacky way might work: writesf~ in raw (headerless mode) mkfifo foo.raw (read mkfifo manual) lame foo.raw (if it accepts raw input) careful with deadlocks/SIGPIPE I could always record to wav and run a script afterwards to compress and delete the original file, but i'd rather have something more direct. i tend to record in 32bit wav (-bytes 4) to avoid any clipping, then remove dc/normalize/convert later. i tend to hoard things, though...
