Support

If AudioOps saves you time, help fund more device coverage and export hardening.

Small support helps pay for testing devices, Android releases, and time spent making trims and merges more reliable on real phones. PayPal.Me keeps the support path lightweight and familiar.

How it works

2 focused workflows from one landing page.

01

Segment editing

Precise Media3 clipping export by default, with optional FFmpeg packet-copy export for fast preserved-format edits.

Preview playback with play, pause, stop, seek, and waveform-backed sliders.

02

Audio merge

Media3 audio-only composition export that concatenates the merge list.

Reorder items, remove individual files, or clear the list before export.

Features

Everything AudioOps handles, workflow by workflow.

Workflow 1

Segment editing

Precise Media3 clipping export by default, with optional FFmpeg packet-copy export for fast preserved-format edits.

  • Open one audio file from the Android document picker.
  • Preview playback with play, pause, stop, seek, and waveform-backed sliders.
  • Adjust start and end times with a two-thumb range slider or typed timestamps.
  • Choose whether export keeps the selected range or removes it from the source file.
  • Choose precise M4A export for closer cut boundaries or fast preserve-format export when source extension preservation matters.
  • Fine-tune trim boundaries with -10s, -1s, -0.1s, +0.1s, +1s, and +10s controls.
  • Set the current playback position directly as the trim start or trim end.

Workflow 2

Audio merge

Media3 audio-only composition export that concatenates the merge list.

  • Build a merge list from multiple files chosen on the device.
  • Reorder items, remove individual files, or clear the list before export.
  • Preview the merge list as one continuous playback session.
  • Export the full merge list as a single output file with metadata copied from the first item when possible.
  • Cancel active exports and resume from the saved result state for open/share/restart actions after completion.

Quality and reliability

Release confidence is built into the workflow.

This same release hardening mindset carries through local checks and device-level export validation.

FAQ

Common questions about AudioOps.

Which audio formats work?

AudioOps supports MP3, M4A, AAC, WAV, OGG, and FLAC. Precise segment export writes M4A, while fast preserve-format export keeps the source format when packet-copy trimming can do so.

What happens when the original format cannot be preserved?

Fast preserve-format editing falls back to AAC in M4A when a packet-copy edit cannot complete. Precise segment editing already exports AAC in M4A.

How are repeated export names handled?

Generates suffixed names like _01, _02, or _m01 until a free file name is found.
