The Audio Replayer is an audio/video repeat player optimized for language learning.
It reads audio files or mp4 video files such as mp3/m4a/wav/FLAC supported by iOS and shows the waveform, allows you to listen to them visually, and automatically recognizes and shows the voice segments, making it easy to know where the sentence starts and ends.
This app is designed to be suitable for studying English or learning multiple languages and is easy to use.
