A2DP Volume vs Sapfir
Side-by-side comparison of two open source alternatives
A2DP Volume
Automatically adjusts the media volume on connect and resets it on disconnect. This is done so that stereo streaming audio can work properly. Intended primarily for car Bluetooth systems. It can read out text messages using Text To Speech (TTS) services while you are connected. Each paired Bluetooth device or virtual device (home dock, car dock, power connection, or headset plug) can be configured to your liking. There is a manual on the website. A secondary feature is the ability to capture location information so you can find where you left your car. The location can also be automatically captured when exiting Car Mode on your Android device and read by any app that understands GPS data.
Sapfir
Record or import breaks and vocals, chop them and export a sound font to make beats using Helio sequencer on your phone or tablet. Can analyze key and tempo, apply highpass and lowpass filters and normalize gain.
