iziCast is a versatile audio and video broadcaster. You can broadcast audio from the internal microphone, external audio devices, audio files and Audiobus compatible apps to Icecast, Shoutcast and RTMP servers. Live video from your camera can be broadcasted to any RTMP compatible service, such as YouTube, Twitch, Facebook and Telegram. Any of the supported audio sources listed above can be combined with your live camera. When using RTMP you can decide if you want to use one of your device cameras as video source or simply an image. In case of an image it is up to you if you want to stream a single image, the album cover of the current track or just a black image to save bandwidth. The image can be changed during the broadcast and you can even let iziCast write text like the current song on the image. Besides that, iziCast comes with a lot more features. Have a look at the list below to find out what else iziCast can do. If you have any questions or suggestions feel free to contact me at izicast@danielnoethen.de The following features are included in iziCast: • Supports internal microphones • Supports external multi channel audio devices • Supports video streaming from your device camera • Supports audio files • Sound Board with up to 16 sound pads • Supports Icecast 2 and Shoutcast 1 & 2 (legacy mode) • Supports Liquidsoap based internet radio platforms (e.g. Airtime/Azuracast) • Supports RTMP/RTMPS (YouTube, Twitch, Facebook, Telegram, etc.) • Supports Audiobus • Supports audio recording • Supports Push To Talk • Preview and share your audio recordings • Provides multiple effects via In-App Purchase (10-Band EQ, Delay, Reverb, Limiter) • Supports MP3 (bit rates from 8 kbps to 320 kbps) • Supports AAC (bit rates from 96 kbps to 320 kbps) • Supports AAC+/AAC-HE (bit rates from 24 bps to 80 kbps) • Supports OGG/Vorbis (bit rates from 16 kbps to 320 kbps) • Supports FLAC (Free Lossless Audio Codec) • Shows you the input audio volume on its level meter • Shows you the used traffic and file size of a session (tap the dot matrix text) • Shows you the number of current and peak listeners • Automatically reconnects on connection failures • Allows you to update the song information • Allows you to apply gain to the input volume • Allows you to mix multiple audio sources with individual volumes • Supports monitoring Which external audio devices are supported? Basically, every class-compliant audio device is supported. Manufacturers will usually indicate whether a device is class-compliant or not. If you cannot find information about class compliance, a good rule of thumb is that an audio device is class-compliant if it does not need a driver to work on macOS. So, if your device works on macOS without a driver, it will also work on your iPhone or iPad with iziCast.
