Voicemodem -> .wav

Post by Dennis Allerka » Fri, 03 Apr 1998 04:00:00



Hi!

I wrote a script which runs my voicemodem (Pearl V1433VQE) as an answer
machine on my Linux server. Therefore I use vmcp from the packet voice-0.6
by Niccolo Rigacci.
But now I want to forward the incoming voice messages to my e-mail accounts.
Therefore I have to convert these messages, which are saved in a modem
specific format and can only be heard again with the same modem, into a
standart format (e.g. .wav).
Has anyone dealt with this problem before? I'm lookiong forwrd to every hint
to this topic...

Bye, Dennis

I don't know if this helps, but I was able to use sox to convert the
GSM files my USR created in to WAVs. I have no idea wether Pearl use
the same GSM format or not though.

PS I think that it may have been a patched sox, but I'm not sure.

Thank you for your help.
But someone told me to use the voice tools of the latest mgetty packet, with
some little changes in the source code I made it. Now I use a combination of
rmdtopvf and pvftowav.

1. Timidity: mid -> wav -> mp3?

Hi all,

I know this isn't 100% Linux-related but it's close enough :-)
As you all know, Timidity is a program that allows cheesy SB16 cards to
play midi's at acceptable quality using GUS patches. It is available
of course for Linux, among others.

I've been trying unsuccessfully to create mp3 files from midi's.
Converting mid -> wav is possible with something like:
   timidity -Ow1S -s 44100 -id -o file.wav file.mid

This creates a "file.wav" - which unfortunately l3enc does not like.
wavplay or splay will play this although these players complain something
about mismatch in speed/frequency. Running l3enc on the wav-file results
in error - something about "invalid wave parameter".

So does anyone have better luck on this?
Thanks for any comments or suggestions and happy holidays everyone :-)
