Voice Recorder is a free Android app developed by Wachi.Apps that provides an easy and wonderful recording experience with high-quality sound. It also offers playback capabilities and several features, including audio recording, editing, and sharing, import audio files, and bookmarking selected records.

The app supports three recording formats: M4A, WAV, and 3gp. The M4A format is encoded with AAC audio codec, which provides good quality and small size. The Waveform Audio File Format (WAV) is an audio file format standard for storing an audio bit-stream on PCs and stores audio data uncompressed. The 3gp format is also supported.

Users can select the sample rate, bit-rate (for M4A only), and stereo in settings, and the selected preferences directly affect the record file size. The app also features beautiful colored themes to customize the design and improve the user experience.

With Voice Recorder, users can record and playback in the background, and the app displays the record waveform. Overall, Voice Recorder is an excellent option for those looking for a straightforward, high-quality recording experience on their Android device.
