Loading remote audio files from URLįor one example way to display waveforms for audio files on remote URLs see #22. There is currently no plan to integrate this as a 1st class citizen as every app will have different requirements, and WaveformImageDrawer as well as WaveformAnalyzer are as simple to use as the views themselves. If you do have very strict performance requirements however, you may want to use WaveformImageDrawer directly instead of the build-in views. This will be more than fine for 95% of typical use cases. Keep in mind though, that this approach will calculate and render the waveform twice initially.

use SPM: add and set 'Up to Next Major' with '12.0.0'.

If you're feeling in the mood of sending someone else a lovely gesture of appreciation, maybe check out my iOS app 💌 SoundCard to send them a real postcard with a personal audio message. On the off-chance though, that using my library has brought joy to you and you just feel like saying 'thank you', I would smile like a 4-year old getting a huge ice cream cone, if you'd support my via one of the sponsoring buttons ☺️ 💕 I'm doing all this for fun and joy and because I strongly believe in the power of open source.
