Frequently asked questions

Music feedback

Costax records a private video breaking down your track — mix, arrangement, sound design, or whatever you ask them to focus on. It lands in your inbox and you can watch it whenever you want, as many times as you like.
Early sketches are often the most valuable to get feedback on, before you get lost in too many iterations — but finished tracks work too if you want a second opinion or to get on the artist’s radar.
MP3 or WAV, any length. Add a note and links when you upload so Costax knows exactly what to focus on.
Most feedback arrives within a few days. If Costax hasn’t responded within 7 days, you’re automatically refunded.
