Operating System and Hardware Support

Eff is compatible with Windows 8 or newer together with Server 2008 R2 or newer, and Intel-based Mac OS-X for OS versions 10.8 up to 10.11. From V6.5, Eff on Windows is a 64 bit application and so only compatible with 64 bit versions of Windows. The OSX operating systems are all 64 bit so there is no issue on Mac.

In terms of required hardware, Eff is very fast, in particular for audio only files, so a fairly basic computer is fine. For MOV and MXF files, which could exceed a few GB in size, then a faster system would be preferable, but the basic laptop will be suitable for evaluation purposes. The number of channels of audio has a major effect on processing times. For example a MXF file with four stereo pairs will take about four times longer to process than a similar file containing just one stereo pair. Dolby™ E encoded soundtracks are also slower to analyse, as Eff uses Dolby™ libraries to convert the audio to PCM, measures and corrects, then uses the Dolby™ libraries to re-encode.

Emotion Systems products can only be used on computers built with Intel-based hardware.


An increasingly large number of facilities are now using Eff, so if you are interested, it might be worth asking others for their views! Alternatively, we do have short term evaluation versions available for both Windows and Mac platforms, so please contact us.
