## What is JoinSound?

Join audio files into one, in the order you want.
Trim each one, then save as M4A, MP3 or WAV.
Simple, and your files never leave your iPhone.

JoinSound does one thing: it puts recordings and songs back to back and saves them as a single file. Pick audio files, or use the share sheet in another app and choose JoinSound. Drag to reorder, trim the start and end of each file or keep only the parts you need, then listen to the whole join and save.

WHAT YOU CAN DO
• Join audio files in the order you choose, and drag to reorder
• Trim each file on its waveform, or keep several parts of one file
• Play any file right in the list, and tap the waveform to jump
• Preview the whole join before saving, with marks where files meet
• Match loudness, so quiet and loud recordings sound even
• Shorten long silences in each file in one tap, after seeing where they are
• Save as M4A, MP3 or WAV, then share or save the file
• Matching files join to M4A without re-encoding, so quality stays the same
• Bring audio in from other apps with the share sheet
