doubt on lossless encoding+wma decoding

[jay_jay]

1)i have a 22khz,20kbps wma file.i want to change its sampling rate to 32khz,lossless.is it possible?,is encoding to wav lossless?can achange in sampling increase its quality?

2)does besweet inputs wma streams?
which is best resampler.mp3 encoder.

change its sampling rate to 32khz,lossless
Short answer : no.
is encoding to wav lossless?
More or less. Transcoding itself is, but additional info, like replay gain values, is lost.
can achange in sampling increase its quality?
Downsampling reduces quality.
Upsampling does not improve quality. It is, however, a worthy option in some situations. Google for 'creative+44.1 kHz'.
does besweet inputs wma streams?
Is there a good reason for not experimenting that yourself ? :D
resampler
Try Naoki Shibata' s SSRC.
mp3 encoder
Try LAME.

BTW, please try to :
--- make the life easier for the readers of your posts...
--- not ask "what's the b35t... " :p

1) That question escapes what the concept of lossless means. The audio won't "sound" worse if you upsample it but there will be no gain in quality whatsoever. The process is not lossless per se as the actual info is changed when upsampled.
Decoding from that WMA to WAV can be considered lossless.

2) Not as far as I know..

3) Don't ask what's best :readrule:

Cheers.
