Full description

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 phone. 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. Press and hold to drag and 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, press and hold to drag and 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 to the Music/JoinSound folder, ready to share • Matching files join to M4A without re-encoding, so quality stays the same • Bring audio in from other apps with the share sheet PRIVATE BY DESIGN Everything happens on your device. Nothing is uploaded, there is no account and there are no ads. FREE Join 2 audio files with up to 2 parts each, match loudness and save as M4A, free. JoinSound Plus (one-time purchase, no subscription) • Join as many audio files as you like • Unlimited parts per file • Save as MP3 and WAV • Shorten silences

What's new

Shorten long silences in each file in one tap. See where they are first. Listen to the result before saving, and smooth the joins between files. Saving keeps going when you leave the app, and you can pick up where you left off. Waveforms load faster and are easier to read.
