How can I get AudioKit to stream an audio file from a remote URL?

阅读更多关于 How can I get AudioKit to stream an audio file from a remote URL?

I'm trying to play audio files from URLs in an iOS app (Swift 4). I'd like them to buffer and play while downloading. And I quite like AudioKit, but for the life of me and I can't figure out how to make it read remote files. Any suggestions? You can't find it because its not there. We've never implemented any streaming functionality. It could be added though, and a number of people like yourself would be quite pleased. Consider contributing some code if you manage to work it out. We can offer you membership to AudioKit's Slack group during development if you wish. If you only need to stream

阅读更多关于 Cracks in webaudio playback during streaming of raw audio data

问题 I have a server sending chunks of raw audio over a websocket. The idea is to retrieve those and play them in a way to have the smoothest playback possible.

阅读更多关于 Google Cast slow for some streams

问题 I have an Android app which plays live streams from web (mostly icecast) via Google Cast. Everything worked fine and fast, but now it takes much longer time for some streams to start (make sound). This may be somehow related to the Chromecast firmware upgrade as my Chromecast device got updated to the latest version (1.32.124602) recently. This is how I play stream via Cast: MediaMetadata metadata = new MediaMetadata(MediaMetadata.MEDIA_TYPE_GENERIC); metadata.putString(MediaMetadata.KEY

I have a mp3 file, so I need to play it, and display an equalizer (like in attached image). So playing is not problem, but I have no idea how to measure power of current playing sample's dBs based on frequency. By which steps I can get data for displaying dBs of current sample?

Here is examples of what I want to achieve: https://www.youtube.com/watch?v=7oeb-OIOe-0 https://www.youtube.com/watch?v=PwmUhTDr0Y0 The standard way to transform from time domain to frequency domain is a Fourier Transform .
