Editing a Sound Liaison 'Pure' DSD recording.

This week, I edited a session recorded in DSD format for the first time. It is a recording of Iman Spaargaren on saxophone and clarinet accompanied by Peter Bjornild on double bass. The recording was made with the “One-Mic Recording” technique using a Josephson C700S.

You might think that editing in DSD format is impossible, and based on the format itself, that would seem true. However, Merging, a Swiss-based company, has developed a solution. They’ve created software that enables both recording and editing in DSD format.

Here’s how it works:

The DSD files are converted in real-time (real-time sample rate conversion), allowing you to edit them as if they were PCM files.

Now, it’s possible to cut and paste sections of the files.

You can even crossfade between the files.

But here’s the real innovation. With Pyramix software, the final result is saved as DSD files.

What originally started as DSD remains as DSD, with no alterations to the audio. Any crossfades or fades at the beginning and end of a song, which were edited in PCM, are converted back to DSD.

The final result is a 'pure' DSD file, with only the crossfade sections being a brief piece of audio converted from PCM — usually just a few milliseconds.

We at Sound Liaison primarily record jazz music (in Hi-Res), where editing is minimal. We typically use entire takes, or sometimes select themes from other takes. As a result, the final product is nearly 100% 'pure' DSD.
