Loudness Compliance

Are you tired of loudness compliance fixes that compromise your audio quality? It’s time to take this process away from the playout centre and move it upstream.

Emotion’s loudness compliance tools ensure that your content’s integrated loudness falls within the required broadcast loudness standards, without compromising the audio experience. Available in the Eff product and as a module within Engine, our loudness tools have been verified by Netflix, are compatible with worldwide standards (including ATSC A85, CALM, EBU R128) and support legacy PPM and VU measurements.

Online Delivery

Do you prepare files for online delivery? Engine can simplify and automate a variety of commonly required tasks, making it easy to meet any platform’s delivery specifications.

Engine can convert any input stream format to any output stream format, can flexibly reorder channels according to your requirements, provides the ability to change the number of audio channels and can insert various types of metadata into supported file types, including channel layout data and language tags.

Standards Conversion

Why use costly edit suite tools to convert file-based content when Engine can automate the process?

Engine automates the traditionally challenging process of converting media from one frame rate to another, maintaining the original video whilst providing impeccable audio to match. Our methodology has been developed in consultation with post-production facilities and is trusted by customers around the world.


Playout systems require a standard input format, yet files are often supplied in a wide range of formats. Let Engine automate your file normalisation.

Converting the different input formats into the required standard needed for playout – or ‘normalising’ these files – is often done by editors working in expensive edit suites. But the process can be entirely automated using Engine, including the ability to add audio channels to your media files and upmix or downmix soundtracks.

Dolby® E Applications

Now you can enjoy the full functionality of Dolby E technology within file-based workflows, without any of the inherent complications.

Because Dolby E was originally designed around hardware and real-time solutions, transitioning this technology to file-based workflows can be challenging. But not with Engine. Engine covers all your essential Dolby E requirements and has modules available for Dolby E encoding, Dolby E decoding, and for Dolby E guard band correction. Full access to Dolby Digital Plus metadata is provided, and you can also obtain comprehensive XML reports of all metadata.

Dolby Digital Professional & Dolby Digital Plus Professional

Engine provides a simple solution to adjust Dolby Digital Pro and Dolby Digital Plus Pro encoded audio.

Files that contain common formats of Dolby Digital Pro and Dolby Digital Plus Pro can be processed in Engine for loudness compliance to normal worldwide standards. Engine also supports the encoding of PCM audio into these formats with the same flexibility.

Upmix & Downmix

Are you looking for a cost-effective way to create a surround sound mix from a stereo soundtrack?

The move to surround sound audio delivery can cause problems for broadcasters dealing with legacy content that’s only available in stereo. Returning to edit to create a surround sound mix is expensive and relies on access to the original master audio, but Engine provides a high-quality, automated solution to this problem. By incorporating world-leading upmix technology into Engine, we can produce a very stable and natural sounding 5.1 mix without destroying the original stereo image. Engine has an equivalent solution for creating stereo where only a surround track exists.

Channel Mapping & Muting

Mapping your channel layout to meet playout centre requirements has never been this easy.

Engine’s channel mapping module provides a flexible and easy-to-configure method of remapping your channel layout. Audio can be treated as groups of channels, in mono, stereo or 5.1 format; groups can be swapped or duplicated and selected channels can be muted using our easy-to-use editor.

Channel Replacement or Extraction

Preparing multilanguage media shouldn’t mean you have to spend extra time in the edit suite.

Engine provides a fully automated and faster-than-real-time method to insert audio from an AIFF or WAV file directly into your media or to extract chosen tracks from your files. This is particularly useful when preparing different language versions of content for global distribution. Engine can also be used to apply language tags to each track.

Commentary Track or AD Solutions

Meet OFCOM and FCC regulations with audio and video description mixes that work on any device.

Whether they’re referred to as audio or video descriptions in your part of the world, preparing the commentary track used to describe the video content for visually impaired audiences can be tricky. Because devices like tablets and computers don’t have the ability to stream the description track in parallel to the main soundtrack, a separate mix has to be created to combine the commentary and original audio. Engine’s AD mix module provides a range of solutions for premixing the commentary using a standard Pan/Fade control track, or can create a control track from a commentary track for use with set top boxes.

Video on Demand (VOD) Solutions

Easily adapt content created for terrestrial or satellite transmission to VOD applications.

File preparation for VOD has some characteristics that differ from regular broadcast, dictated by the different playout mechanisms employed. A common requirement is for files with 16 channels of audio, even when only a single stereo mix is provided. Engine takes this task out of the edit suite with automated workflows that can be customised to your needs.

These applications are supported by Engine’s powerful automation capabilities, provided through both a comprehensive API for integration with third-party tools and via watch folders for instant automation efficiency.

We’re always working with our clients to develop new modules and functions to meet the industry’s evolving needs.
