How to use this workflow
Keep space after the event
Choose an ending with a clear stop. Retain enough trailing silence to hear a quiet decay.
Change one reverb control
Compare two exports with only one setting changed. Record preset, decay, pre-delay and mix.
Listen beyond the dry stop
Compare the tail separately from the initial hit. Note where the next event would mask it in the actual arrangement.
A decay with known mathematical checkpoints
Tail begins a 660 Hz tone at 1.000 s with envelope 0.3 exp(−2u), where u is seconds since onset. At u = 0.5, 1 and 2 s, the nominal envelope is 0.110364, 0.040601 and 0.005495. The carrier itself crosses zero repeatedly; these values describe its envelope.
This is an authored exponential control, not a room response or the tool’s reverb engine. The file ends at 5 seconds. File duration alone cannot establish the audible decay time, and the last quantized samples may be zero.
Swipe or scroll sideways to read all columns.
| Checkpoint | Action or value | Interpretation |
|---|---|---|
| 1.5 s file time | 0.110364 envelope | 0.5 s into decay |
| 2.0 s file time | 0.040601 envelope | 1 s into decay |
| 3.0 s file time | 0.005495 envelope | 2 s into decay |
Use the result in the actual mix
If an exposed tail sounds pleasant but masks the next phrase, reduce mix or decay and compare again in context. Increasing monitor level to chase the last quiet samples invalidates the original level comparison.
The reverb tool allocates an effect tail in its export. That allocation is not a certified RT60 measurement. Keep pre-delay separate from decay and preserve the full saved file when checking the ending.
