We're pleased to announce the release of Rocket Broadcaster 1.4. This major update adds the brand new Broadcast Audio Processor, an automatic configuration backup system, and improved connectivity for Radio Mast.

Here's what's new in Rocket Broadcaster 1.4.0:

Broadcast Audio Processor PRO

Our brand new Broadcast Audio Processor improves the sound of your stream by providing consistent loudness and mastering of your audio. By using ITU BS.1770 loudness metering (LUFS), our unique hybrid two-stage AGC ensures your stream hits a consistent loudness target, so listeners can hear it comfortably on all devices.

The Broadcast Audio Processor also includes a Multiband Compressor and Peak Limiter, with 9 easy presets, to help you shape the sound of your radio station. Our signal processing chain gives your stream that "radio" sound, making it loud and clear on a variety of devices.

For more information, check out our page on the Broadcast Audio Processor and the documentation for it.

Other New Features

Soundcard Clock Drift Compensation

When using different input and output devices, Rocket Broadcaster now transparently compensates for clock sync drift. This solves an issue where mixing different input and output devices could sometimes result in a choppy stream over long periods of time.

Enhanced Connectivity for Radio Mast

We've added a new "Radio Mast" stream connection type, which provides better connectivity to Radio Mast servers. It will automatically choose the closest server region for you and failover to the next nearest region if your ISP loses the ability to reach it.

Automatic Config Backup System

We've added a system to automatically save a backup of your settings on your PC, to help prevent losing your settings if your PC is shutdown improperly or your settings are corrupted. If your settings are corrupted and a backup is available, you'll be asked if you'd like to restore from backup. This prompt is on a timer which automatically accepts the backup option after 45 seconds, to help ensure operation is automatically restored without human intervention.

Other New Features:

• Stream Diagnostic - We've improved the explanations of some common issues in the Stream Diagnostics.
• More keyboard shortcuts - Added keyboard shortcuts for mute mic (CTRL+M), opening the Broadcast Processor (CTRL+B), and monitoring master output (CTRL+O).

Bugfixes

• Fixed a rare crash that could happen on certain systems over long periods of time.
• Fixed a rare issue that could cause settings to get lost during unexpected shutdown.

• Fixed an issue caused by attempting to record with less than 30% disk space free

Introducing HLS at Radio Mast

We're also pleased to announce HLS support for MP3 and AAC streams is now available as a free upgrade for all users on the Radio Mast Streaming Network. HLS provides a better listening experience for mobile listeners by allowing listeners to seamlessly switch between Wifi and cellular networks interrupting playback, as well as improving battery life.

Getting an HLS audio stream is now easier than ever before - simply create a stream on Radio Mast and connect your encoder. Your MP3 or AAC stream will be available not only as a conventional HTTP(S) stream, but now also as an HLS stream. No reconfiguration or expensive extra software is required, and this feature is available at no additional cost to Radio Mast users.

RSAS Status Update

RSAS is still under heavy development and we've quietly released many alphas of the 0.1.21 series, which is now likely to evolve into a proper "1.0" release. This next release will see improved HTTP/1.1 support for serving static files and podcasts, support for preroll and postroll jingles/ads, the option to auto-stop relays, a significant number of bugfixes, and with any luck, some form of HLS support. All of those feature are already complete, but HLS still needs some polish before we can ship it. Stay tuned for RSAS 1.0 news!

We're pleased to announce our first release of 2020, Rocket Broadcaster 1.3.3. This cumulative update was developed in close collaboration with a number of radio stations, and is focused on improving support for high-end soundcards and adding support for two new metadata formats.

Here's what's new:

Soundcard Compatibility Improvements

Audiophiles will be pleased to hear that we've improved support for high-end soundcards. We've also added support for mono inputs, which is particularly useful if you need to capture many streams from a single soundcard (via multiple instances of Rocket Broadcaster Pro).

• Added ASIO Support
  • Improved compatibility with high-end soundcards via the ASIO audio API. ASIO can now be chosen in the preferences, and supports up to 96 kHz.
  • Improved support for UAD soundcards.
  • ASIO channel names are now shown, which is especially helpful on soundcards with many inputs.
• Reintroduced Windows MME and DirectSound audio APIs, to improve compatibility with certain legacy soundcards with older drivers.
• Added mono input support. This allows you to capture from individual mono inputs on a soundcard, and automatically handles upmixing to stereo if needed.

New Metadata Ingestion

Metadata can now be ingested from more automation and metadata systems:

• Added Artic Palm CSRDS XML metadata support
• Added Enco DAD XML metadata support

Other Improvements

• Fixed saving Shoutcast 2 artwork and "private stream" preferences
• Increased the max number of saved recordings
