Free live audio planning tools
Calculate timing, levels, spacing, file size, layouts, and cue sheets, or trim a local audio file directly in your browser.
Audio ducking level calculator
Calculate a real music ducking target from measured music and voice levels plus the voice-over-music margin you want.
Audio fade timing checker and preview
Check whether fades fit, compare linear and equal-power curves, visualize the envelope, and preview a local audio file without uploading it.
Audio file size and limit calculator
Estimate export size from common MP3, AAC, and WAV presets, compare it with a size limit, and inspect a local file without uploading it.
Audio loop duration calculator with gaps and crossfades
Read a local loop length or enter it manually, then calculate repeat or target duration with real gaps and crossfades between plays.
dBFS calculator: linear amplitude and gain
Convert a peak-referenced dBFS level to normalized linear amplitude, apply a gain change, and see whether the result crosses 0 dBFS.
Show run time calculator
Add segment durations and transition buffers to calculate a complete show run time and spot the longest blocks.
Sound cue sheet maker
Turn a simple timed cue list into a normalized CSV cue sheet that can be copied or downloaded.
Sound cue spacing calculator
Check a timed cue list for tight gaps and overlaps using each cue start time and duration.
Soundboard audio trimmer
Trim a local audio file, add short fades, preview the result, and download a WAV without uploading the source file.
Reorderable soundboard layout planner
Build, reorder, preview, and export a cue grid that preserves the exact performance order you choose.
