How-To: Make MP3s about 1/5 smaller to fit the PSP!
I have found a way to make the MP3s of your favorite music about 1/5 smaller, yet have great quality, so you can store 5 times more music on your PSP! Hope you guys like this tutorial! I've worked a bit trying to figure out which options to use.

First off, you can use any major music program like Sound Forge to do this, but I have found a way around for a freebie, for the people who do not want to buy the programs.

1) Download this program called, GoldWave. I have uploaded it to my file space.

http://www.gamegoer.com/mobiledeviant

At that link, download the gwave510.exe and lame_enc.dll. The dll is required.

2) Install GoldWave using gwave510.exe. Then copy the lame_enc.dll to the install directory.
(C:\Program Files\GoldWave)

3) Get your MP3s ready. Start GoldWave, and go to File->Open. Then open up your MP3 files. Next, just go to File->Save As. On the bottom, below where you put your filename, there will be a drop bar, where you can choose the quality. Choose this quality and save the file anywhere you want.
(Layer-3, 32000 Hz, 40 kbps, mono)

4) When I saved a 5.54MB file with that quality, it came to about 1.15MB. That is about 1/5 of the original size!

5) Do more files, and enjoy!

As a musician I would not recommend people doing this to their MP3s. First off - mono. That's not good - you loose all of the stereo-field which is even more apparent using headphones than listening using conventional speakers. Secondly - 40kbps.. that's.. not a lot of bandwidth, even if it is mono.

I tried to re-encode some of the songs I know by heart and I simply can't stand listening to them because they sound so awful, with encoding pops and that unmistaken MP3 "fluff" that comes with using low bandwidth encoded files.

If you really want to squeeze the size of your music-files, I'd recommend using a little higher bandwidth, and definitively using stereo-files. Just compare the original to the mono-file and you'll hear how flat and awful the mono-file is.

Also; you can use the LAME-encoder directly without resulting in warez-ing a commercial sound editing-program.

Get this LAMEenc WinAMP-plugin and do it all directly from WinAMP.

1) Just load up the files you want to convert in the playlist

2) Press "Ctrl-P" to open up the preferences-panel, select "Plugins > Output", select "Lame MP3 writer plug-in" and click "Configure"

3) Besides what is already on by default In the options-panel, select the following:

- Resample - 32000 Hz
- Variable BR
- Min Bitrate - 64
- Max Bitrate - 112

4) Select an output directory, close the preferences-panel and click Play in WinAMP. Your file(s) will now be reencoded.

How much can you save? Well, with these settings I re-encoded a 04:09 song that was in 192 kbit from 5.98 MB to 3.40 MB. That's 2.6 MB less, or close to half the size. Purists might still object to the quality, but it's pretty damn good and you can fit twice as many MP3-files on your Memory Stick this way.

But it is only 1/5 the quality...

I use ATRAC3 or whatever it's called. It shrinks them down a bit, and doesn't seem to lose much quality.

The difference is minimal

Does PSP support OGG format? If it does, OGGs are smaller than mp3 and sound better as well (Did a audio codec final paper for my Multimedia class, and OGG kicked mp3's ass in compression/quality)

if you're using the headphones that came with the psp, there won't be any major drop off in quality. But if you took the time to listen with a decent pair of headphones, or even a well made lowend pair (like the ksc 35/75) you will hear a sizable difference. Audio-wise the psp is a respectable if unremarkable device.
If one of the steps is converting to mono, this truly would sound awful. Why pay so much attention about the visuals being stellar if the audio is going to be like the original gameboy?
