mp3 resampling

[Amerzone]

I have recently downloaded from KaZaA an mp3 file with the following characteristics: vbr, MPEG 2.5 layer 3, 11025Hz. It does not play in Winamp 2.81, other DirectX based players play it fine.

Is there an easy way to transcode it to MPEG I layer 3, 44100Hz?

Resampling can be done if you decode to WAV then reencode. You can do all that within RazorLame.

Thanx for the advice. I tried to decode with BeSweet and Cooledit 2.0 Pro. The size of the resulting wav file looks somehow strange to me, in the sense that:

- Original mp3 (mpeg 2.5, 11025 Hz, stereo) = 6,471,808 bytes
- Decoded wav (PCM, 16-bit, 11025 Hz, stereo) = 14,600,000 bytes (sizes differ marginally between BeSweet and Cooledit)

...nevertheless, the wav file plays fine.

Now I want to resample to 44100 Hz, yet Cooledit doesn't give me the option to pump up the sampling rate, only to go down... :confused:

If you don't need super high resampling quality, you can reencode in RazorLame and set there the sampling rate to 44,1KHz.

don't transcode the file!
download the mpeg winamp plugin that appears in the audiofaq, or try your luck with other players like foobar2k.

@ DJ Bobo --> You are right, RazorLame indeed does the trick! :p
@ DSPguru --> Thanx for the hint about the MAD input plugin (it works just fine with the original mpeg2.5 file)
