Audio Loop Seam Planner
Plan loop duration after removing a tail overlap for a seam crossfade.
Your inputs
Calculation results
Formula & assumptions
Loop period = original duration − overlap duration; this does not process audio.
Values use the specified units. Calculations use floating-point arithmetic. Check input measurements and formula assumptions before applying the result.
Compare your scenarios
Save up to five results to compare changes side by side. Scenarios stay in this tab until you clear or reload it.
Using Audio Loop Seam Planner
Plan loop duration after removing a tail overlap for a seam crossfade.
- Enter original loop, overlap, sample rate using the units printed under each field.
- Choose Calculate, or enable live updates. Review the result labels and formula assumptions.
- Save scenarios to compare up to five variations, then copy the report or download JSON or CSV.
Example
Original loop: 4 seconds Overlap: 50 milliseconds Sample rate: 48000 samples per second New loop period · seconds: 3.95 Overlap samples: 2400 New loop samples: 189600
Questions & answers
What does Audio Loop Seam Planner calculate?
Plan loop duration after removing a tail overlap for a seam crossfade.
Which units should I enter?
Original loop uses seconds. Overlap uses milliseconds. Sample rate uses samples per second. Convert values to these units before calculating.
Which formula does it use?
Loop period = original duration − overlap duration; this does not process audio.
What does the included example show?
Original loop: 4 seconds; Overlap: 50 milliseconds; Sample rate: 48000 samples per second. Result: New loop period · seconds = 3.95; Overlap samples = 2400; New loop samples = 189600.
Can I compare different settings?
Yes. Save a scenario, change the inputs and save another result. Up to five scenarios are compared in this tab; they disappear when you reload or leave.
Can I export the calculation?
Copy the JSON report or download JSON and CSV with inputs, result labels and numeric values. Processing uses local JavaScript; no calculation request is sent to our server. Displayed values use up to 10 significant digits; exports retain JavaScript numeric precision.
