I was reading HN for more than 3 years now, without posting, so no need to register.

CBMS networks is a startup company that develops chords detection technology and Chords! is one of the product that is based on this technology. I am co-owner of CBMS networks and fully developed Chords! as a separate product.

Now the question is could you call Chords! a startup? From mine perspective yes - since it is brand new product. If this is not according to HN definitions, than I am sorry for posting it here.

Thanks. He wrote very useful comment.

Don't know him personally, but based on what he wrote sentence "found it do an 'interesting' job determining the chords of the song" sounds like we are doing pretty good in chords extraction, right? :)

Thank you for information. We hadn't considered this path.

You are right that this task is not solved yet. You may read about our technology at http://www.music-ir.org/mirex/2008/abs/cbms_cover_song_id.pd...

Our tests showed that 92% of the time we show correct chords, which is obviously not a 100%.

If you will have a time, give it a try, it works really well.

We actually analyze the mp3, no need for Winamp DSP at this stage. WE need DSP to mix chords to song, so you hear exact place.

we are working on some web based application, down side is that you have to be connected.

This is not solution to pro, rather to beginners. It might take a while (forever?) to find chords for not so popular song.

Only winamp supports DSP API, so you could mix chords to actual song. Rest players are less open, but more popular. We are thinking to support other media players without mix functionality

This is in our plans to have Mac support.

Could you send me any mp3 to [email protected] and I will send you chords back.

We plan to add online service.
