Why is sample rate 44.1 Hz and bitrate 144 kbps not supporte
Just curious why a project sample rate of 44100 kbps and bitrate of 144 kbps combination is not supported by the MP3 file format in Audacity. Anyone know?
Re: Why is sample rate 44.1 Hz and bitrate 144 kbps not supp
MP3, I assume?
144 kbps may not be a valid MP3 bitrate. This page says:
144 kbps may not be a valid MP3 bitrate. This page says:
MPEG-1 layer III sample frequencies (kHz): 32 48 44.1
bitrates (kbps): 32 40 48 56 64 80 96 112 128 160 192 224 256 320
That should be 44.1 kHz.ample rate of 44100 kbps
Re: Why is sample rate 44.1 Hz and bitrate 144 kbps not supp
There are three MP3 codecs: MPEG-1 layer III, MPEG-2 layer III and MPEG-3 layer III. Each use slightly different encoding methods and support different sample rate/bit rate combinations. As you can see here: http://lame.cvs.sourceforge.net/viewvc/ ... usage.html, 144 kbps is a supported bit rate only for MPEG-2 layer III. The highest sample rate supported by MPEG-2 layer III is 24 kHz. "Normal" MP3's are MPEG-1 layer III.

Re: Why is sample rate 44.1 Hz and bitrate 144 kbps not supp
Perhaps the developers skipped support for that bitrate at 44.1 KHz because of Microsoft's not-so-perfect algorithms, having a proclivity for confusion when alphanumerics are similar: e.g. 44100 and 144 (?). I once typed a filename similar to that of a system file, with a legitimately different file extension, yet the OS read it as a sys file...just my guess that MS is the limiter. I already visited the links kindly provided, but maybe I overlooked something. I research them further. Thanks for responding.
