How it helps

Use audio joiner on the go

Audio joining is useful for combining voice notes, stitching short recordings, adding an intro/outro, or creating a single file from multiple clips.

Files are joined in the order selected. All decoded clips are resampled to the first file sample rate and mixed into the same channel count.

Processing runs in your browser after the file is decoded. Browser support depends on the file format, codec, device memory, CPU, and current browser features. For sensitive or confidential audio, review privacy practices carefully before using any online tool.

How to use

How to use this tool

Open the tool page. Choose the audio tool you need from the tools menu or related tools section.
Add your audio. Upload a supported audio file, choose multiple files for the joiner, or record from your microphone on the voice recorder page.

Formats

Browser-supported audio input

The upload field accepts common audio extensions, but the browser must be able to decode the actual file. MP3 and WAV are the safest choices. OGG, OPUS, M4A, AAC, M4R, FLAC, and AIFF vary by browser and operating system.
