Grep For Mp3 Mac Audio Players

So the encoding/decoding of the music files is done on the proc and that takes cycles. M3u extension.Due to its age, MPG is no longer covered by any patents, that is why both Mac and Windows applications along with many hardware support MPEG video and audio.Itunes, and all mac audio players, are processor hungry becuase macs don't use a separate sound card (like peecees do). Txt file with the same contents as above with the. M3u playlist is nothing but a.

Command file anywhere you'd like, and even add it to the login items (in sys prefs). Open up terminal, and do the following command: `chmod +x ~/iTunesFix.command`. Save the file as 'iTunesFix.command' inside your home directory. Copy and paste that into a text editor (make sure, if you use textedit, that its not saved as an rtf and that no formatting is added).

In terminal, type: `ps aux | grep iTunes.app`. If you find itunes is overstepping its bounds, you can alter its nice value. So the encoding/decoding of the music files is done on the proc and that takes cycles. Itunes, and all mac audio players, are processor hungry becuase macs don't use a separate sound card (like peecees do). If you wrap it inside an applescript, i think you can avoid that, but i'm not very familiar with applescript.

If you repeat the renice step several times, iTunes will gain a high nice value (up to positive 20), and consequently will use less proc time. The next command to type is `renice +1 PROCESSID`, replacing 'PROCESSID' with the number you found in the first command. The first number printed is the 'process id'.

It's combination of a higher quality but less optimized algorithm running on a slower clockspeed processor that only has one FPU vice two. I just disabled hardware acceleration on my athlon box and winamp still averages 0% of the cpu.Like encoders, not all decoders are created equally. If you want to return iTunes to its normal nice-ness, use `sudo renice 0 PROCESSID` (note: sudo may require you to type in an administrator's password).It's not necessarily hardware acceleration.

Just like iTunes, unlike CL mpg123.So what's with the other 8%? iTunes probably uses them to do the song name scrolling. It even has a very simple GUI which means that the app has to listen for events etc. Mpg123 (no altivec) uses 5% while AT THE SAME TIME ON THE SAME MACHINE itunes uses 10% with quality enhancments and equalizer TURNED OFF.It uses an altivec optimized mpg123 library and uses 2% CPU. It's like boxing with both hands tied behind your back, but baby you've got the nicest gloves on back there!1) So why isn't it optimized? Altivec has 4x single precision FP (or whatever is used to decompress mp3).2) I think you misunderstood me.
