For the musically inclined members of the QJ community, here's something new for you to try out. Rocamatics created a guitar effects processor for the PSP. Called GuitarBox v1.52, it will process electronic sounds in real time and add specific effects to them as desired by the user.According to Rocamatics' readme, GuitarBox v1.52 carries the following effects with it:
- Noise Suppresor
- Phaser
- Distortion (overdrive type)
- Delay
- Equalizer (3-band)
In any case, why not try it out with a microphone first and see how well it does, then let us know what you think. Enjoy!

I´m Rocamatics the developer of GuitarBox. The app´s MAIN purpose is to process an electric guitar signal (however, you can use a standard mic to test it!!!). Please, I need your feedback to improve the app!!
BTW, Im participating in the PSP-HACKS Homebrew Contest 2007.
Regards!.

Gotta to try it tomorrow
Is this a port of some existing algorithm or you wrote it from scratch ?
Could you give more details about sampling frequency? How about the input/output latency ? Did you measured it exactly in ms ? Is it noticeable ?
Is there a way to implement backing tracks playback and process guitar input sound at the same time ?
Thanks

I was wondering if you could work in a "tap tempo" feature for the delay. Maybe just double tap one of the shoulder triggers twice to the beat to set the delay time, that would make this way usable as a live effect.
Thanks for all the hard work.

Keep up the good work!

Latency is noticable, but still fully usable.
Well done Sir, you 'll have my vote.

Is it worth my time to try and make that connector to try this? Or is it still too early with the app and I should wait until there are later versions, etc.
I have all the pieces of hardware I think - so it wouldn't cost me anything.

Thanks Guys!!
Some details in the CODING:
I use the PSPSDK, GNU Compiler and VS2005 as the IDE.
I've made some research and I found many algorithms for the effects, I analyzed them, and adapted for the PSP.
The sampling frequency is 44khz, the latency depends of how many effects are you sing at the same time... im still in the stage of optimizing the code. I cannot tell you the latency in MS.
It is possible to include a backing track.. however I need to optimize the effects first.
The next version will contain AT LEAST Chorus and a decent Tuner.
Regards.
