Audio Recorder pro

Audio Recorder Pro is an audio recording and playback app that offers two recording formats: M4A and Waveform Audio File Format (WAVE , or WAV). In settings, you can set the sample rate and bitrate (for AAC only), as well as select between mono and stereo. These preferences directly affect the file size of the recordings.

This app offers a range of features, including recording and playing back audio, displaying a waveform of the recording, renaming recordings, sharing recordings, importing audio files, listing recordings, and adding recordings to bookmarks. Additionally, recordings can be made in the background, allowing users to continue using the app while the recording is in progress.
