STUDIO TOOLS
Calculators and references we actually use in sessions — free for every artist, producer, and engineer in the Valley and beyond.

EQ EAR TRAINER
The skill that separates engineers from everyone else: hearing where a sound lives. Pink noise plays with one band boosted +12 dB — A/B it against flat, then name the band. Ten rounds. Headphones recommended.
SESSION COST CALCULATOR
Engineer always included. Slide to your session length — longer sessions earn a better rate.

| NOTE | STRAIGHT | DOTTED | TRIPLET |
|---|---|---|---|
| 1/1 | 2000 ms | 3000 ms | 1333 ms |
| 1/2 | 1000 ms | 1500 ms | 667 ms |
| 1/4 | 500 ms | 750 ms | 333 ms |
| 1/8 | 250 ms | 375 ms | 167 ms |
| 1/16 | 125 ms | 188 ms | 83.3 ms |
| 1/32 | 62.5 ms | 93.8 ms | 41.7 ms |
TIGHT VOCAL SLAP
Try a 1/32–1/16 delay (62.5–125 ms), low feedback.
REVERB PRE-DELAY
A 1/64 value (≈31.3 ms) keeps vocals upfront before the tail blooms.
CLASSIC 1/4-NOTE ECHO
500 ms, or the dotted 1/8 (375 ms) for that U2/trap bounce.
STREAMING LOUDNESS TARGETS
How loud should your master be? Pick where your music will live — integrated loudness and true-peak targets per platform.
-14 LUFS
INTEGRATED LOUDNESS
-1 dBTP
TRUE PEAK CEILING
Normalizes to -14 LUFS by default. Louder masters get turned down — keep dynamics instead of chasing volume. Premium users can disable normalization, but mix for the default.
Rule of thumb: master for impact, not numbers — platforms turn loud masters down, so crushed dynamics buy you nothing. Want it handled? Our mastering service delivers streaming-optimized masters.
