What each tool is for
Relato · audiobook narrators
Stop, rewind, find your place, punch in. Then hours of listening to cut the false starts out again.
Relato keeps your place and keeps the last read of every line. No retakes left to cut out afterwards.
See Relato →Estrofa · songwriters who sing
Lyrics in a notes app, rhymes in the browser, the melody in voice memos. Every switch costs the line you were holding.
Estrofa checks rhymes, syllables and clichés with the reason shown, and never rewrites a line you did not ask for.

Mixing by value means looking away from the sound to read a figure, then listening again to check.

Engineer
Sombra Audio is built by someone who makes music every day and has 25+ years of software engineering behind it. A tool gets made when something keeps getting in the way: a retake you have to cut out later, a verse that no longer scans, an EQ band you can only set by number.
Need audio software built for you? Custom work goes through Mulhacén Labs, the studio that publishes Sombra Audio.
sombra-dsp
Estrofa helps you write and record the song. The plugins are for mixing it, and the sound packs give a track something to start from.
In the open
Every tool is built in the open. Read how it is made, and see what comes next.
About
Sombra Audio is Barry Faassen, a software engineer with 25+ years of experience who also produces electronic music. Relato, Estrofa and the plugins all come from the same desk, and what you write back lands on that desk too.
There is no committee and no investor roadmap behind it. A tool gets built when it fixes something that came up in real work, and the roadmap above is the whole plan.
Relato and Estrofa are in early access. Read or write with them now and tell me what gets in the way.
Relato early access €29, pay once. Estrofa's price is not set yet.
