Drag & drop audio files to merge
Supported: MP3, WAV, AAC, OGG, FLAC, WMA, M4R, M4A
Multi-segment audio production requires reliable sequential joining without gaps or quality loss. Merge Audio concatenates any mix of MP3, WAV, OGG, and FLAC files into a continuous track — the fastest path to assembling podcast episodes, audiobook chapters, and DJ sets without a full DAW.
For gap-free merging, ensure all segments share the same sample rate and channel count. Mixing 44.1 kHz and 48 kHz sources can introduce timing drift. Use Audio Converter to normalize all segments first.
The tool resamples all inputs to match the first file's sample rate during merging. For exact control, pre-convert all segments to a uniform format using the Audio Converter before you merge.
Generate a silent WAV of the desired duration using the Advanced Audio Studio, then include it between segments in the merge sequence to add precise, controlled gaps.
No hard limit — performance depends on combined file size and available device RAM. A typical podcast episode with 3 segments of around 10 minutes each merges in a few seconds on standard hardware.
