Analysis without pm2 or super pv?

#1

I’m using Spear to create SDIF analysis files but as far as I can tell Spear’s output is limited to partial tracking analysis. I’d like to find software to perform F0 and transient detection, and at the moment I can’t afford the IRCAM programs. I considered SMS - it will do F0 detection - but I’ve been unable to build it on the Mac Mini. The SoX DFT analysis is helpful with the transient markers but I’ve been unsuccessful getting the markers into an SDIF file (probably because I still have a lot to learn).

Any suggestions ? I’m a Mac Mini M1, btw. I do have a Linux machine here as well but I’d like to keep my work on one machine at this time.

Dear Dave,

Very good question. It might be possible to convert Sox DFT analysis into sdif. But i am no specialist in this matter. Can you send me a small file of such an analysis in order to see what can we do about it. I know that OM have such tools to build an sdif file starting from a text file.

One lead: Use OM-Sox library (very unstable - don’t play the SOUND object for the moment) and check out the SDIF help patches (from the om’s help menu) and most particularly the 09-sdif-write-3 patch.

That’s what I’m working with now. I think I need to learn how to fine-tune the SoX analysis for best results from specific WAV files.

Dear Dave,
I fixed the Sox player issue (OM 7 abruptly quits when playing is over in the Sound object under Sox player mode):

redefine this method in /sources/player-om608.lisp as so:

(defmethod player-stop ((engine (eql :soxplayer)) &optional play-list)
;(print “soxplayer stop”)
(call-next-method))

removing:

; (declare (ignore view))
; (sox-kill nil))
