Web Radio Processing

For webradio processing, we offer two processing engines based on the HQ SOUND 192 kHz engine, a patented SOUND4 technology, precisely designed and optimized for streaming applications.

The X1. CL is a lightweight and flexible solution, perfectly suited for more limited budgets. The processing chain consists of an advanced wideband AGC, a 4-band equalizer, Tone FX, Stereo FX, 3-band processing, a 4-band limiter with special high-frequency management to reduce streaming artifacts, and finally, a super-efficient final limiter with an Over Drive mode allowing for a more solid sound when necessary. In short, everything you need to make your streams sound perfect!

The IMPACT .CL, our flagship product and the most sophisticated and powerful audio processor currently available on the market, meticulously designed to meet the strictest requirements of professional broadcasters, recognized and considered by countless professional clients worldwide as the undisputed standard and absolute reference in the online audio broadcasting and professional streaming industry. The processing chain consists of an advanced wideband or 2-band AGC, a 4-band equalizer, Tone FX, Stereo FX, a 6-band de-clipper, a 6-band processor, a 6-band limiter, a 4-band equalizer, and finally, a super-efficient final limiter with an Over Drive mode allowing for a more solid sound when necessary.

The best balance in terms of CPU requirements...

Reality always imposes compromises. In streaming processing, limiting CPU consumption is essential for optimal efficiency, particularly when managing hundreds of channels simultaneously. The x1 stands out as the world's most performant processor, combining exceptional sound quality and low CPU consumption: less than 250 MHz per instance! In practical terms, this allows running 400 instances on a 16-core processor running at 5 GHz, a feat unique to SOUND4! The IMPACT .CL consumes approximately 450 MHz per instance, which also makes it the most optimized processor in the world!

As a recognized leader in the field of streaming encoding, we are proud to offer the industry's most complete and advanced solution. Our expertise allows us to meet the most demanding needs of professional broadcasters. 

The SOUND4 streaming engine, developed after years of research and innovation, delivers high-quality content via a multitude of protocols, including Icecast, Shoutcast, RTP, RTSP, UDP, SRT, HLS, as well as numerous other standard and emerging protocols. This versatility ensures maximum compatibility with existing infrastructures. 

Our solution also supports a wide range of high-performance audio codecs including MP3, AAC, HE-AAC, Opus, Vorbis, and FLAC, thus offering an optimal balance between sound quality and bandwidth efficiency for each broadcasting scenario.

The streaming engine offers six completely independent encoding configurations/mount points, allowing simultaneous broadcasting of six streams.

Metadata management is natively integrated into the SOUND4 streaming engine, offering a comprehensive and efficient solution for processing information associated with audio content. Thanks to scripts that are fully editable and customizable by the user, the system can seamlessly connect to any external automation system, thus ensuring maximum flexibility and flawless interoperability.

Need to integrate a watermark into your audio streams so they appear in official audience measurements? Are you looking for a reliable solution that preserves your sound quality? Our Web Radio solutions integrate this essential feature as an option! Thanks to our advanced technology, all your broadcast content will be correctly identified and counted in audience reports, thus maximizing your visibility to potential advertisers.

Furthermore, unlike other solutions that may alter sound quality, SOUND4's watermarking process preserves the acoustic integrity of streams while incorporating the necessary data for audience tracking.
