Finally, click OK to save the clips and return to the main interface.

If you have multiple M4A files and want to merge them into one clip, you can click the Merge button above the audio file to open the Merge window. Here you can select the files and click the middle Merge button to create one pack. Repeat the process you can merge the multiple files into several larger clips. Finally, press the bottom Merge button to save the merged packs.

If you want to change the audio format to a more compatible format, you can press the big format image on the right of the interface and head to the Audio category to choose one format you like. Then press the inverted triangle button to specify an output folder. Finally, hit the Run button to start the process.
Audacity is a free audio editor that can run on Windows, Mac, and other operating systems. It is open-source software that can edit audio in WAV, AIFF, MP3, AU, FLAC, and OGG Vorbis. With this powerful audio editor, you can cut, merge, and record audio files.
But Audacity doesn’t natively support M4A files. So to edit M4A files in Audacity, you need to install the optional FFmpeg library. Otherwise, you need to convert M4A to a supported audio format like WAV or AIFF.

WavePad is another free desktop M4A editor for Windows and Mac. You can use it to copy, paste, delete, insert silence, and cut the file. It also allows you to add audio effects to M4A, such as echo, reverb, amplify, reverse, and normalize. In addition to editing M4A files, WavePad is also an M4A converter that can convert from and to M4A format. But WavePad is only free for non-commercial use. If you want to use it for professional use, you need to upgrade to the paid Master version.

Besides the desktop audio editor, people often want to find an online solution because they don’t need to download any software on their PC. Although online tools may be more convenient and free, it still has some drawbacks. The online M4A editors require a stable internet connection and may limit the editing times and file sizes. Here I find two online M4A audio editors for you.
AudioMass is a free, open-source audio editor that has basic audio editing features. The UI is intuitive and without annoying ads. But the limits are also obvious. This web-based M4A editor only supports exporting the edited files in MP3 or WAV format. To edit M4A files, you just need to drag and drop the file into the interface and start editing. You can add effects to the audio, cut the audio and insert silence in the desired parts. Finally, export the edited files.

The Aconvert audio editor can run on any browser and the editing process is quite simple. It supports uploading audio files from a local drive, online URL, Google Drive, and Dropbox. But the Aconvert audio editor only supports cutting M4A files. And it lacks a visual view when cutting the audio files so you cannot directly select the wanted parts. Moreover, the interface of this online tool is full of annoying ads.
