Merge and combine multiple audio files into one — drag & drop, crossfade, no upload
Audio Joiner is currently under development. Meanwhile, try our existing tools:
Audio Joiner will let you combine multiple audio files into a single track directly in your browser. Whether you need to merge podcast segments, combine music tracks, or join voice recordings, this tool handles it without uploading your files to any server.
The tool uses the Web Audio API to decode each audio file into raw PCM data, concatenates the audio buffers with optional crossfade transitions between tracks, and encodes the result. All processing happens in your browser using JavaScript — no server involved.
Merging podcast episodes from separately recorded segments. Combining music tracks into a continuous mix. Joining voice recordings or meeting notes into a single file. Creating audio montages from multiple clips for presentations or social media.
While Audio Joiner is being built, try our Audio Trimmer, Audio Converter, Text to Speech, or Voice to Text.
