+mp3write~.dll is a MPEG I Layer III (mp3) file writer.

+mp3write~ has been compiled for Linux using LAME 3.92.
+The newest version of LAME can be found via freshmeat.net

+
+ using mp3write~ external for Pure Data
+
+Open the test-mp3write~.pd to understand how it works.
+In this patch, you must send the messages to mp3write~
+in the following order :
+
+1/ append|truncate if you wish to change file creation options ( default is append )
+2/ open /my/file
+3/ start
+5/ pd dsp 1
+4/ stop : the tag is written at this stage
+
+Parameters sent to mp3write~ object :
+
+ Sampling Rate (Hz):
+Possible values are 48000, 44100 and 32000. If Pd runs at a different sampling
+rate, LAME will resample the signal. Default value for mp3 sampling rate is Pd's
+sampling rate.
+
+ Bitrate (kbit/s):
+Possible values are 32, 40, 48, 56, 64, 80, 96, 112, 128, 160, 192, 224, 256
+and 320. Default is 224.
+
+ Mode:
+Possible values are 0 (stereo), 1 (joint stereo, the default), 2 (dual channel)
+and 3 (mono).
+
+ Outlet:
+The outlet outputs an int, which the number of bytes written in this session.
+this might be different from file size if you're using append mode.
+
+
+ Known Problems :
+
+All combinations of samplerate, bitrate, quality factor will not be accepted.
+
+ALLOWED QUALITY FACTOR :
+
+ -q <arg> <arg> = 0...9. Default -q 5
+ -q 0: Highest quality, very slow
+ -q 9: Poor quality, but fast
+ -h Same as -q 2. Recommended.
+ -f Same as -q 7. Fast, ok quality
+
+ALLOWED SAMPLERATE/BITRATES
+
+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
+
+MPEG-2 layer III sample frequencies (kHz): 16 24 22.05
+bitrates (kbps): 8 16 24 32 40 48 56 64 80 96 112 128 144 160
+
+MPEG-2.5 layer III sample frequencies (kHz): 8 12 11.025
+bitrates (kbps): 8 16 24 32 40 48 56 64 80 96 112 128 144 160
+
+Furthermore, it seems that high quality factors will not work
+with this release of lame ( 3.92 ).
+The same errors can be obtained with the command line :
+lame -q 1 file.wav
+outputs errors and mp3write can't do better.
