[Csnd] newish track

So here’s something from me. It was recorded in December, but I only did post-production on it a few weeks ago.

It’s a live recording, digital piano and synthesizer (Novation Summit), post-produced with Csound, playing with stereo width (the new ms2st opcode) and added convolution reverb.

Wonderful!

I will have to play around with ms2st, I did not know about it. How does it work to produce width? How do you reckon it compares to doing such enhancement with “hilbert”?

Oh, I just read the docs for ms2st…I guess it’s for when you already have a mid track and a side track…whereas, I am actually creating those “from scratch” with hilbert (real and imaginary being subtracted to produce a side), and then creating a copy of that difference, inverting, and that would be one channel vs. univerted being the other…both of course having some of the original mono mixed in.

It’s very simple actually.

The st2ms produces an MS pair from a stereo recording, then the ms2st can convert back to stereo with adjustable width (0 - 1) where 0.5 is normal
stereo. Nothing fancy, Menno designed it and I added it.

I tried it with the stereo tracks from the synth (the recording was 4-track with piano and synth separated). It helped to emphasise the side sounds, and then using an envelope I could introduce some changes over time.

Yes, but you can create an MS pair from stereo, then recode it with varying width.
That’s what I did.

Many thanks for sharing! I enjoyed your track a lot. The piano sits very
well in its space. Sometimes I got that very realistic impression of
almost being able to walk forward and touch it. Also nice to hear the
Summit in this setting.

Thanks also for mentioning the ms2st opcode. That means I can throw out
my little UDO. The less stuff to include and gather before writing
something the better! :slight_smile:

Best wishes,

Jeanette

Thanks, Jeanette. It was Menno’s idea that we needed MS decoders and that we should split them in two so
that the decoding code be done with varying amounts of width.
