How the Hotline works

Three steps between you and better ears.

The process is simple, the feedback isn't. Every report is written by a qualified professional, not an algorithm, not a generic checklist.

01 · Send it in

Upload your track

Submit a link to your work-in-progress via Dropbox, Google Drive, SoundCloud or similar. Add a short note: what you're stuck on, what you've already tried, how you want it to feel.

02 · We listen

Reviewed in person at Rue Boyer

Your track is auditioned across a range of reference monitors and consumer devices, to help maximize translation wherever your listeners may hear it.

03 · You get a report

Written feedback in 24 hours

Receive a detailed, timestamped breakdown with practical next steps, plus an option to book a private video call with the reviewer for deeper insights.

The listening room

Award-winning listening rooms.

Every submission is reviewed in person at Rue Boyer Studios, an award-winning facility designed by WSDG. The signal chain and the acoustics are calibrated to reveal what sounds great on your headphones but falls apart in the real world.

Your track is tested across a range of reference monitors and consumer devices, so the notes you get back translate across every listening context your audience lives in.

Reference monitors Augspurger · ATC · Yamaha · Auratone
Consumer devices Earbuds, laptop speakers, phone
Immersive rig Dolby-certified 7.1.4 Atmos, available on request
Acoustic design WSDG — the team behind Jungle City, Electric Lady, and more
Who's on the other end

Ears you can rely on.

Reports are written by our in-house team, working producers, songwriters, and engineers.

P

Producers

Arrangement, sound selection, aesthetics, references... What is this song trying to be, and what are its strengths and weaknesses?

S

Songwriters

Top lines, lyrics, song structures, chord progressions... The stuff that happens before the mix ever gets to the desk.

E

Engineers

Clarity, dynamics, tonal balance, imaging, loudness, translation... Where the mix breaks and how to fix it.
