Features

Merge Any Audio Format

Combine MP3, M4A, WAV, FLAC, OGG, Opus, WMA, and other FFmpeg-readable formats in one ordered timeline.

Smart, Lossless or Studio

Smart mode avoids unnecessary encoding, Lossless Copy fails closed on incompatible inputs, and Studio Merge handles mixed formats and effects.

Precision Waveform Trim

Thin range handles keep the waveform visible. Use exact times, keyboard nudges, horizontal panning, and 1×–32× zoom for accurate cuts.

Metadata, Cover & CUE

Write title, artist, album, year, genre, comment, and cover art. Create a CUE sheet with markers adjusted for trims, gaps, and crossfades.

More Features

Straight Interface

A clear timeline keeps file order, duration, trim ranges, output format, and processing mode visible. Drag clips into order, preview transitions, duplicate or remove items, and save the complete job as a reusable project.

Audio Merger

Combine up to 200 clips into MP3, M4A, WAV, FLAC, OGG, Opus, or WMA. Smart mode preserves compatible streams; Lossless Copy rejects incompatible inputs; Studio Merge handles mixed formats, trims, effects, and loudness.

Batch Workflow

Add files or folders, reorder large timelines, apply non-destructive trims, and reuse saved projects. The app validates inputs, writes one separate merged output, and leaves every source file untouched.

Quality & Output Control

Choose bitrate, sample rate, channels, codec, and container. Add accurate LUFS loudness normalization, fades, silence gaps, or crossfades. Smart mode avoids unnecessary encoding whenever the requested result is compatible.

Precise Trim & Waveform Zoom

Trim without changing the originals. Thin handles keep the waveform visible; exact time fields, keyboard nudges, horizontal panning, timeline ticks, and 1×–32× zoom make precise cuts practical.

Local, Free & Private

Works locally on Windows 11 and 10—no account and no audio upload. Source files are never overwritten. FFmpeg provides broad format support and is disclosed with an official-project link in About.
