Thanks Christian !

 I'm posting this on behalf of Logan McBroom who is having some difficulty logging in at the moment ( weird server issues, that we SHALL resolve..)
Anyway, his question:

When transforming a signal via the phase vocoder, knowing
that instantaneous frequency is calculated via phase differences, how is
frequency calculated on frame 0?
I am having a hard time following the c
code for this.

This might be of interest to some here

Hello All,
Those of us using Firefox may have recently noticed a nag notice in the password part of the login suggesting the site is insecure.
This is new in Firefox 52 I believe.
The solution ( and I woud advise all users to switch to a secure connection anyway!) is to use this url

https://unstablesound.net/cdpforum

The "https" being the secure part.
As always, we seek to make this a secure and friendly place for discussions.

Happy CDP'ing
Simon

These are updates to all CDP soundfile programs (apart from the Windows GUI ones), with the all-important modification to sfsys to make the
environment variable CDP_SOUND_EXT optional, defaulting to wav. It also restores proper behaviour preserving sample type (24bit, floats etc) and
use of the -f prefix for output files, which had somehow got lost in the previous release. The change to the environment variable essentially
means programs can now be used directly without an installation/configuration step.

Just copy all executables to the existing _cdprogs folder.

I should add the usual caveat of making a backup first.

Happy sonic mangling!
Simon
