Taking the quality of TV audio to a whole new level with CSR’s MAPX™ and ZIRENE® SOUND by AM3D
AM3D is CSR's first partner to offer audio
enhancement solutions on MAPX™, CSR's high quality audio system-on-chip
(SoC) for soundbars, docking speakers, AV-receivers, home theatre
systems, and integrated audio systems.
This is great news for developers of TVs and
soundbars as the combination of the MAPX processing power and the
audio expertise of AM3D's
ZIRENE® SOUND solution will bring the sound quality of
soundbars to an all new level. CSR spoke to Jacob N. Andersen,
Senior Vice President at AM3D, to find out more about ZIRENE®
SOUND, what the partnership means for the business and his outlook
on audio industry trends.
CSR: Can you please give a brief description of ZIRENE®
AM3D: ZIRENE® SOUND is a HD quality audio
enhancement solution. It significantly improves the output sound
quality of audio playback devices such as smartphones, tablets,
TVs, soundbars, Head Mounted Displays, headphones and other kinds
of devices in which audio is an essential part of the user
experience. The solution is purely software-based and easily
integrated into a device.
CSR: How does it help manufacturers improve the audio
quality on their products?
AM3D: The demand for small, slim and portable
audio devices means that audio playback capabilities often differ
significantly from those intended by the creators of the original
media content. For example, stereo music and multi-channel audio
are produced with specific loudspeaker arrangements in mind. These
are not directly achievable with small devices or headphones. Other
limitations may be caused by low acoustic output power or reduced
bandwidth capability. To overcome the inherent performance
limitations of audio devices, ZIRENE® SOUND offers state-of-the-art
audio enhancement technologies to optimise the audio playback
capabilities. ZIRENE® SOUND significantly increases the sound
quality by post-processing the audio signal in the device. ZIRENE®
SOUND includes high-quality features to:
- Create surround sound virtually for headphones and stereo
- Enhance audio content to boost voice dialog and equalise
- Enhance playback capabilities by equalising and boosting bass,
treble and level
In addition to the ZIRENE® SOUND software solution, AM3D offers
tuning tools for quick and easy adaption to each device model.
CSR: In what ways is CSR MAPX helping to achieve
AM3D: CSR MAPX is a family of highly integrated
SoC designed for audio applications. It offers such a large amount
of processing power and professional audio interfaces that we were
able to implement our algorithms on MAPX without compromising audio
Furthermore, MAPX's extensible architecture means our algorithms
can run in conjunction with other standard audio decoders, allowing
cost-effective but fully-featured solutions based around one single
Finally, MAPX's toolset allows us to tune our algorithms in
real-time, thus considerably reducing the tuning effort required
for each project.
CSR: How do you see the audio market developing in the
next five years?
AM3D: After several years where audio has
suffered with poor quality because of the demand for still smaller
and slimmer devices, we see a market shift where audio once again
will be used as an important competitive parameter when companies
seek to differentiate their products. This shift is happening
because thin high-resolution displays have become an everyday
commodity. Manufacturers therefore need to come up with a new
selling point as the wow-effect declines. Audio is the natural
successor to fill up this wow-gap, as there is a demand for HQ
audio and 3D audio from the manufacturers as well as the consumers.
We believe that audio in the next five years will boom and take the
market into a new dimension.
CSR: In what ways will your partnership with CSR help
you achieve your own long-term objectives?
AM3D: Being part of CSR's eXtension partner
program helps our unique audio software to reach a much wider range
of consumers; CSR has a large choice of platforms for Soundbars,
Speakers, Headsets and Home Theatre Systems, and AM3D's products
are part of CSR's offering.
