@phantom, Yes it was indeed Madonna that sang this acapella. Due to laziness I downloaded a filtered version already but it was not entirely filtered, hence used soundforge with some plugins to remove the rest.

@Mcmeatloaf. In its current implementation (Well since frodigi2, I have improved the routine which overall gives 10% higher quality) instrumentation sounds ok. Where it suffers still is in complex audio - many frequencies etc, and basslines. That said, it is attempting to cram everything into 3 channels with 4 waveforms.

@Oswald. I will be implementing additional heuristics to minimize the frequency fluctuations. In its current form, it is using a crude form of frequency adjustments. A quick workaround - which is already implemented is a longer window search or/and 25hz mode

cool one again. btw what if you try to predict that what way frequencies are going rising / sinking, and try to use that trend to remove warbling. similar could be done to other qualities.

How well does it work for different musical instruments?

My first thought when I heard the music was... Did Madonna sing this Acappella?

My next thought was, what program you used to remove the instruments (I use guitar pro).

Then, while listening to it, I swear I could hear the bleeps and blips that made this what it is. There were a few places in the song that seemed higher, but that could be blamed on my emulated C64.

Overall? It's simply amazing what you have done here. THIS will change a lot of things when you finally make the routine available to the public.

GREAT work here.. Thanks for sharing :D

It sounds great! Lyrics and voice are very clear.
I am sure that if one day humanity will create a teleport (encoding a human form to elementary particles and decoding it back) it will be your work, or your child ;-)

The quality of the audio would be significantly many times higher when using dual sid due being able to represent the source audio more accurately due to more waveforms and frequencies. (But.. I am not really interested in non-stock hardware)

There are some issues with having speeds higher than single speed as mentioned before in the original frodigi. I have overcome some of the distortion using other methods such as lookaheads and comparisons between future chunks to attempt to keep frequencies identical and in the same channel etc, but in essence, would require a completely different method which has its own limitations.

What about 4x multispeed version? ;)

Since the release of Frodigi, I had implemented many changes in the encoder for the PC that generates compressed audio data that can be played back on a C64.

For anyone that has not heard the previous frodigi demo, this demonstration produces "audio samples" by changing waveforms and frequency only once per frame in order to recreate the audio.

More technical details to follow. Use new SID for higher quality

About this site:
CSDb (Commodore 64 Scene Database) is a website which goal is to gather as much information and material about the scene around the commodore 64 computer - the worlds most popular home computer throughout time. Here you can find almost anything which was ever made for the commodore 64, and more is being added every day. As this website is scene related, you can mostly find demos, music and graphics made by the people who made the scene (the sceners), but you can also find a lot of the old classic games here. Try out the search box in the top right corner, or check out the CSDb main page for the latest additions.
