I had a very similar problem with ffmpeg and IMA4, I don't know if it's related but the symptoms were quite similar to what you describe. I filed a bug report with the ffmpeg crew and the noise issue was eventually resolved. Pure speculation here, but it's possible there is shared or similar codec code somewhere in the mix. You might try with a recent ffmpeg build just to compare. Cheers, Alex ________________________________ From: Michael Bishop <mb...@hi...> To: sox...@li...

Hi folks, I'm new to this list and I've run out of ideas for converting some files I have. I've got some .ogg files and am trying to convert them to .wav files (using IMA-ADPCM). When I do it in Audacity, it sounds fine, but through sox, it sounds horrible with a crackling in the right ear. Here is what the Audacity parameters look like: Format: Uncompressed Files Options: Header: WAV (Microsoft) Encoding: IMA ADPCM And here is what I'm doing with sox: sox --norm=-3 music.ogg -e ima-adpcm music.wav The audacity file sounds great and it is the sox that has the cracklings. Any ideas as to why I might get this horrible sound? Thanks in advance, _ michael ------------- Here is the soxi output: mbishop$ soxi c1_amb_beach_loop.wav Input File : 'c1_amb_beach_loop.wav' Channels : 2 Sample Rate : 44100 Precision : 13-bit Duration : 00:00:25.03 = 1103930 samples = 1877.43 CDDA sectors File Size : 1.12M Bit Rate : 358k Sample Encoding: 4-bit IMA ADPCM mbishop$ soxi c1_amb_beach_loop-audacity.wav Input File : 'c1_amb_beach_loop-audacity.wav' Channels : 2 Sample Rate : 44100 Precision : 13-bit Duration : 00:00:25.04 = 1104181 samples = 1877.86 CDDA sectors File Size : 1.11M Bit Rate : 354k Sample Encoding: 4-bit IMA ADPCM ------------------------------------------------------------------------------ LogMeIn Rescue: Anywhere, Anytime Remote support for IT.
