64kb vs 128kb audio
In our latest version, audio files have a default bit rate of 64kbps. If the quality of the 64kb file is unsatisfactory or simply unavailable, you may choose 128kbps file, which sounds nearly identical to an untrained ear. Please go back to Home Screen of this app, tap the gear icon in the bottom-left corner to open the app settings, and switch on the "Download 128kb audio". You may turn on and off this switch at any time and it will take effect on download of subsequent audio tracks.
