Understanding Audio Joining
Audio joining is the process of appending audio streams sequentially. Unlike mixing, where sounds are layered on top of each other, joining ensures that Track B begins exactly when Track A ends.
The Power of Crossfades
By overlapping the end of one track with the start of the next, crossfades eliminate the "pop" or silence that often occurs between abrupt cuts, creating a professional playback experience.
High-Fidelity Exports
We recommend exporting as WAV for lossless archiving, or MP3 with a minimum of 256kbps if you're planning to share the file on social media or messaging apps.
