Soundwaves 1.34 has been released on the App Store.
The audio and streaming engine has been rewritten from scratch trying to keep a low energy impact. Battery should last longer than with previous versions, especially when you’re not connected via WiFi. Also, audio will restart automatically after an interruption (e.g. due to Siri or an incoming call).
Last but not least, there’s a brand new icon 🙂
By the way, did you know that you can also play FLAC tracks on iOS 11? 🙂
