iziCast1.11.0 - App Store

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.

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.

Version History • Fixed a startup crash that could occur for some users.
• Improved audio streaming compatibility: Fall back to AAC-LC if HE-AAC is not supported by the current audio settings.
• Fixed an issue where the monitor sound would jump to the phone's speaker even when headphones or another speaker were connected. (You can restore the old behavior in Settings > "Monitor on speaker".)
• Fixed a bug where the internal microphone could no longer be selected while another input device was connected.
• Made the play button in the recording library easier to tap.

- Some audio devices like the Alesis MultiMux 12 USB claim to support 48000 Hz but do not deliver any audio data when initialized with this sample rate.
To fix this, you can set the preferred input sample rate to 44100 Hz.
- If your audio device supports high sample rates like 96000 Hz, you can set the preferred input sample rate to that value and stream FLAC at 96000 Hz.
