He means two "bits" in length, one "on" and one "off".

Well, that would be pretty boring and monophonic at best, most of the 1 bit trackers are more complex, using drums, and more instruments and then using software tricks to blend everything and represent it in a 1 bit output. Ends up sounding pretty cool. Maybe some 1 bit piezoelectric buzzer mods are in order, and THAT would be cool.

Yes, exactly!

what if you could get a 1bit sound engine out of each papu channel. 9 voice polyphony?

Also that.

After some further research and debate I've gone ahead and made what I claim is true 1 but sound (if not necessarily music) using LGPT on PSP. Check out the recording and download the project folder if you dare: http://chipmusic.org/egr/music/1-bit-so … gy-tracker

Ah, yeah that makes sense.

As for calling something 1bit: this is a special "extreme" case where the name is referring to the method of generating the audible sound, toggling the speaker or whatever on and off with no amplitude control. "Beeper music" is probably a less inflammatory and even more descriptive term. Let's go with that instead.

GB is an 8 bit powered machine that outputs sound at bit depth 16.

EDIT: I'm just going to make these sweeping statements with full confidence until someone who actually knows what they're talking about comes along.

Re: 1 bit on dmg-01 (38 replies, posted in Nintendo Consoles)

Not true, 1 bit is the resolution of the output which on zx etc was a beeper but the processor was 8 bit. You can force the output of a gb to be 1 bit with software mixing.

A multichannel 1bit tracker for gameboy would be really cool!

Sony's PSP consoles are lucky enough to have their own LGPT build. The units are extremely well built and feature bright clear screens, rechargeable batteries, and easy USB connectivity for copying projects/samples/new builds. Pictured above are the original PSP-1001 model and the relatively recent PSP GO.

‹ What are the differences between PSP models?

LINK to exhaustive specs on all models: http://psp.about.com/od/hardwarefirmwar … models.htm

There are some differences in models but they are generally only "cosmetic". Here's some things to remember:

1000 - Original "fat" model. Has 32 megs of ram. Storage via Memory Stick Pro Duo. [the most comfortable handheld I've ever used. -ed]

2000/3000 - Updated "slim" models. Has 64 megs of ram. Storage via Memory Stick Pro Duo. 3000 features a built in microphone for if/when that ever becomes important. Both versions have audio and video out (thru a proprietary cable) for big screen piggin'.

GO - Much smaller and with a slide-up screen. No UMD slot which means no moving parts. Has 16 gigs of internal storage expandable to 32 gigs with a Memory Stick 2. Layout feels similar to a GBASP. No A/V out. One nice feature is that the charge cable doubles as a USB cable for PC connectivity.

VITA - [not sure, need to research -ed]

E1000 - Stripped down model with no Wifi, mono speaker, and no A/V out. Matte finish is pretty cool.

‹ How do I run piggy on my PSP?

The simplest answer is "get some custom firmware on there"!
If that is to much work for you (and sometimes it's really a pain) then use HalfByte Loader: http://wololo.net/hbl/
Be sure to download the version that matches your official firmware!

Unless you're very concerned about hearing loss (ya wimp) go to Settings > Sound Settings and turn all the options off. We don't want key clicks or crappy limiting/compression screwing up our hard work.

why not just use a 1-bit tracker? it's not like there's a lack of them.

This is more of a theoretical question, as in "what would it take to 1bit piggy style".

On the other hand, why not just clap your hands and sing?

Re: 1-bit music on the piggy [now with example!] (10 replies, posted in LittleGPTracker)

Hmmm, I see your point. Is it true that the audio output of a 1bit tracker is a sound file with bit depth 1? That sounds obvious but the answer could easily be 'no'.

Edit: Now that I think about it a little better, the answer has to be 'yes' since 1bit trackers are actually just toggling a beeper or dac between on and off. You couldn't possibly get more than 1bit out of it.

Topic: 1-bit music on the piggy [now with example!] (10 replies, posted in LittleGPTracker)

If I set "crush" to "1" on all my samples in a piggy project has it now become 1-bit music? What are the differences between using a 1-bit sample in a typical tracker vs using a 1-bit specific tracker?

EDIT: After some further research and debate I've gone ahead and made what I claim is true 1 but sound (if not necessarily music) using LGPT on PSP. Check out the recording and download the project folder if you dare: http://chipmusic.org/egr/music/1-bit-so … gy-tracker

Actually this is more accurately "voltage spike sound" than 1 bit sound. When the audio circuit is turned off suddenly from a very high gain there is an audible click and that's what I'm actually manipulating. However I firmly believe that this still qualifies as 1 bit.
