Dear All,

We are converting .mpg & *.wav files to *.mp3 with Sound forge 4.5.

Can anybody suggest ideal settings for getting maximum possible
optimized file size for the *.mp3.

Any idea what is the audio codec...encoder used in Sound Forge 4.5?
does that affect the file size of *.mp3....

Any help is appreciated.....

I don't use the SF encoder, but the concepts are the same with any encoder.
There's always a tradeoff between file size and fidelity. The smaller the
file, the worse the sound quality. Your best bet is to experiment with the
various encoding parameters, and find the best balance for the kind of tunes
you produce.

Never mind Sound Forge for mp3 encoding. dBpowerAMP Music Converter is the
ticket, despite the stupid name. Get the Lame MP3 codec for it, and just
right-click on the files you want converted, set the bitrate, and off it
goes, generates the best sounding MP3's at any given bitrate, and it's free!

As for what bitrate to use, it depends on the source sound quality and the
target audience. If it's decent material but just web clips for demo
purposes, 128kbps is standard, but 160 offers marginally cleaner treble if
it's a shorter song/clip. If it's mono you can afford to cut the rate by
more than half, since stereo imaging issues are the first problems to pop up
and are no longer an issue. For super-tiny files go with mono, 8-bit, 32kHz
(you'll have to drop bit-depth and sample rate in Sound Forge) at 48kbps,
about AM radio quality.

For best sound there's no point in going higher than 256kbps. Sonograms of
the compression artifacts indicate that the Lame codec actually renders
cleaner results at 256 than 320, don't ask me why. Beyond that look into
FLAC, a lossless codec that has a WinAMP plug-in so they can be played
without having to expand them, also available for dBpowerAMP for convenient
encoding.

Really? I didn't think you could save as MP3's with version 4.5. I just
upgraded to 6 because it came with the Batch Converter and I had to convert,
maybe 300 files to MP3's for a voiceover client.

Yes you can, if you pay them an additional $29.95 or so. You can upgrade on
line. They give you a key code that unlocks the MP3 function.

This doesnt really relate to what your asking but have you though
about using Windows Media Audio (.wma) files . The free encoder
available from Microsoft is very powerful and *.wma files integrate
into web pages better that mp3 IMHO. Sonically they are the same.

Anyone delivering audio/video from the web should check out the
Windows Media Encoder. It is by far my favorite format.

There were initially two releases of SF 4.5 if I remember correctly, the
standard full release and and OEM release. The full version included the
MP3 plug-in for free, but you had to register it with Sonic Foundry (either
online or telephonically). This version of the plug-in did not offer many
encoding options, but used the Frauenhofer codec. The OEM version required
a separate purchase to be made, but this add-on option is apparently no
longer available.

SF 4.5 also had a batch converter, but it was not nearly as user friendly as
the stand-alone version and you couldn't use SF for anything else until
conversion had completed. So, I wouldn't kick myself for upgrading if I
were you. The increased productivity obtained from non-destructive editing
and separate batch converter are worth the $$. The biggest difference in
respect of MP3 is that they are now using the faster Xing codec.
