Lame MP3 ARM for Zyxel (ARM926EJ-S)

Lame less lame on ARM?

Yes, it is! There in a new compilation of Lame I did a long time ago for Zyxel NAS. This one is especially optimised for ARM cpu that is inside this NAS file server. It's still painful slow but it also is 10% faster than previous version. Here are short results of compressing 600 frames:


root@seagate3tb:/home# ./lame.2 lazy.mp3 lazy.2.mp3
ID3v2 found. Be aware that the ID3 tag is currently lost when transcoding.
LAME 3.98.4 32bits (http://www.mp3dev.org/)
Using polyphase lowpass filter, transition band: 16538 Hz - 17071 Hz
Encoding lazy.mp3 to lazy.2.mp3
Encoding as 44.1 kHz j-stereo MPEG-1 Layer III (11x) 128 kbps qval=3
