Every source. One clock. One microphone you can leave on.

Your voice, a piano, Spotify or a DAW and browser audio land together in one aligned Sangam microphone for Zoom, OBS, Meet and Record. It stays resident all day and costs almost nothing until something actually listens.

What it does

Every app, your interface and your voice in one aligned Sangam microphone for Zoom, OBS and Record. Resident, 1-2 % CPU idle, spectral noise reduction.

Every source, one clock.

Apps, hardware inputs and pass-thru lanes are stamped onto one room-time axis and read at one shared delay, so relative timing between any number of sources is zero by construction. The transport number is shown live, never hidden.

A microphone you can leave on.

Resident and demand-driven: the Sangam microphone is always there, but the capture graph runs only while Zoom, OBS, a dictation tool, the recorder or a monitor needs it. Idle, it costs 1-2 % of a core (measured), so it can stay on through a concert recording or a whole day of lessons.

Record first.

The home screen is the recorder: one button, the exact stereo mix Zoom hears as 24-bit WAV, and an honest health line that stops a failing take and says why.

A voice chain built for teaching and calls.

Spectral noise reduction takes hiss, fan and hum out from under the voice, a true-RMS gate handles the floor between phrases, then tone EQ, a soft-knee compressor and a speech leveler. Zero lookahead except the 10.7 ms spectral pass, which is compensated so the mic never skews against the apps.

Voice, piano and track know their job.

A track (Spotify, YouTube, a DAW) sits on the voice clock as heard. A piano (Pianoteq, MainStage, any standalone instrument) is pulled by the MIDI-to-sound delay measured while you play, so a sung note and a played note land together in the send.

Virtual devices, visual routing.

Create devices other apps treat as real hardware, send any app to any output or channel pair, and see every route as a patch cable. The trick that used to need a $100+ tool, at $59, once.

Founder note

Sangam started as the routing engine behind my own streaming and teaching rig. It is designed around ordinary Core Audio interfaces, browser audio, virtual instruments and the mic input you actually choose for the session.

What's new

  • Every source on one clock: your voice is the clock, a track (Spotify, YouTube, a DAW) sits on it as heard, a piano (Pianoteq, MainStage, any standalone instrument) is pulled by the MIDI delay measured while you play.
  • A microphone you can leave on: the capture graph runs only while a call app, recorder or monitor is listening — 1–2 % of one core idle, measured.
  • Record is the home screen: one button, the exact Zoom mix as 24-bit WAV, a health line that stops a failing take and says why. Three surfaces: Record / Mix / Setup.

Known issues

  • Live playback stays on Core Audio's direct path; Sangam time-aligns the copied mix that streams and recordings receive (one-way transport from about 67 ms with a few sources up to about 136 ms on a large rig, always shown live in the top bar). For self-monitoring use your interface's direct monitor.

FAQ

Sangam, Shruti or GrabIt?

Shruti is control: every app gets its own volume, EQ and output. Sangam is the microphone: routing, alignment, virtual devices, recording. GrabIt is capture and archive. Sangam ignores Shruti's virtual devices, so the two run side by side without doubling anything, and the bundle saves you money.

Does it support my audio interface?

Sangam works with Core Audio interfaces. The first-release test setup requires at least one or two inputs and a stereo output; larger multi-channel setups can be configured in the same patchbay.

What formats does it record?

The current release workflow records clean 24-bit WAV files, as a live mix or separate source tracks.

One-time, really?

Really. $59, three of your own Macs, free updates for version 1.
