What to decide first with EQ

Before reading every EQ article, define the 15 seconds that bother you and the exact symptom. This hub groups the first articles and checks in the same order FUJI° uses before a free audio check.

Limit the symptom to 15 seconds

Do not judge the whole song first. Loop the section where "You are not sure what to send before ordering" appears so the cause and processing change are easier to compare.

Name one job

Use EQ for one sentence such as "How to Send Files for a Mix Request: alignment, naming and references". If there are multiple jobs, separate recording, editing, mixing and mastering decisions.

Define the rollback point

Before moving frequency, level-match before and after processing. A louder setting is easy to mistake for a better setting.

Information that speeds up a quote

A 15-sec audio URL and timestamp
One symptom sentence such as buried, harsh or thin
Both vocal-only and instrumental playback
A reference track and why you like it
Posting date and preferred deadline
