Sometimes, iPhone users may want to create a longer audio track by combining multiple shorter recordings or remove unwanted sounds by splitting and combining only those recordings or fragments they want. There are various apps you can use to join or merge two or more voice memos or sound recordings on iPhone. Here we will use the free version of Hokusai Audio Editor app to show you how to merge and combine multiple voice memos on iPhone. If you have a Mac as well, you can also make use of the desktop version of iMovie to combine voice memos on Mac.
Export voice memos to Files app
You have to firstly select and save voice memos or audio recordings you want to edit from Voice Memos app to the stock Files app. Open Voice Memos on iPhone, tap Edit, then touch to select all the voice memos or recordings, tap the Share icon from the bottom left corner, choose Save to Files > On My iPhone, save the recordings to the root or select a folder to save them.
Merging vs combining audios
By merging voice memos here we refer to mix two audio tracks with each track playing at the same time, layered on top of each other. Combining two audio tracks refers to the process of simply placing two voice recordings or sound tracks one after the other, so that they play sequentially one after the other as part of the same file. Download this free audio editor app onto your iPhone before we use it to merge or join voice recordings.
Merge or mix two voice memos on iPhone
Open the audio editor app, its Projects screen opens by default. Here you can resume your work from previous projects or start a new project.
Tap the Add (+) button at the upper right corner to create a new project. Tap the Import button at the bottom to access its Audio Library, then click Services… to browse to Files app to find and add the first voice memo.
Repeat the steps to add the second and extra sound tracks or voice memos to the app. If you play them in Hokusai now, all audio tracks will play simultaneously.
Tap the Configuration icon at the top right corner, and select Settings, choose the output audio format you like, WAV or M4A/AAC under the Sharing Format section.
Tap the Configuration icon again, and select the Mix Down option to merge all sound tracks into one.
Tap the Configuration icon, then select Share Audio, choose to save it to Files app or share it with other apps you have installed on the iPhone.
Combine voice memos on iPhone
Again go to create a new project in Hokusai audio editor. Then tap Import button, then browse to Files app to add the first voice memo. Before you add the second voice recording, you have to move the playhead over the sound wave to the end of the first voice recording. After that go to import the second voice memo to the audio editor. So the two voice memos will align end to end.
If you play them in Hokusai now, they will play sequentially one after the other.
Repeat the steps when you need to add extra sound tracks, just make sure to drag and drop the playhead to the end of the previous audio.
Alternatively you can also import all voice memos to the audio editor without placing the playhead in advance. You can then scrub the timeline or waveform of the second sound track to select the whole or any part of it, copy the selection, then tap on the end of the first sound track, paste the second voice memos to the end of the first one. In this way, you can also put two or multiple voice memos in the order you like on one track.
Tap the Configuration icon at the top right corner, and select Settings, choose the sharing audio format you like, WAV or M4A/AAC. Tap the Configuration icon, then select Share Audio, choose to save it to Files app or share it with other apps you have installed on the iPhone.
