variable bitrate using external tool for conversion

[neutrox]

I found a script which does audio conversion but for constant bit rate conversion.
Anyone have a good solution to convert some .mp3 files to variable bit rate, 32-320 bit rate?

Conversion done by lame (an mp3 encoder)?

Just replace the parameters to encode in vbr instead of cbr...

[neutrox]

$fopts = "-v";
instead of
$fopts = "-C 160.2"; ?

[highend]

No.

http://sox.sourceforge.net/soxformat.html

so it's e.g. -C -4.2

but read the parameter list to get what you want.

mistake on quoting?
But I get a flash black DOS window popping after running

Code: Select all

run """C:\Programs\sox 14\sox.exe"" 'C:\mp3\Main Theme.mp3' -C -4.2 'C:\mp3\converted\Main Theme.mp3' rate -v 44100";

[highend]

because you left out the $gopts parameter "-S"?

run """C:\Programs\sox 14\sox.exe"" -S ""C:\mp3\Main Theme.mp3"" -C -4.2 ""C:\mp3\converted\Main Theme.mp3"" rate -v 44100";

[neutrox]

no...
I have put a lame_enc.dll into sox folder just in case. No effect.
Any other ideas?
Or tool?

My sox is a "with mp3" support compiled one. Don't know about yours.

Just use lame.exe if sox isn't working for you.
