3. Background






The company was originally set up in the early 90s to commercialize
PhD research from Queen‟s University Belfast, launching the first
generation of aptX codec„s.
New variants of the codec were launched in 1998 and 2007.
Heavily adopted by Broadcast, Professional Audio and
Cinema sectors.
Every Public Service and Commercial radio broadcaster in
Europe, Asia and North America is using aptX.

4. Adopters
Over 24,000 DTS cinema theatres use aptX for 5.1 playback

Technology standard for Voice Over, Post
 Production and ADR i.e. SkyWalker Ranch, Warner Bros,
Pixar, Disney, etc


5. Today
July 2010 – acquired by CSR

6. Milestones – aptX for Bluetooth

2008 saw breakthrough design win with Sennheiser –
210 PX BT headphones launched with aptX Sept
2009. In 2010 and 2011 aptX enabled headphones
from Sennheiser won the Best Wireless Headphones in
the What HiFi awards

More design wins quickly followed from Creative
Labs,Working collaboratively with Creative, jointly won
the “Best of CES Bluetooth” in Jan 2010

June 2010, Apple launch Mini Mac with aptX inside

July 2010, Apple launch Mac Book Pro and Snow
Leopard 10.6.5 supporting apt-X. This enables 20
million Apple users to use apt-X on Source devices.
Aug 2011, Apple launch Lion OS with aptX.

October 2011 Samsung announce Galaxy Tab 7.0 Plus
supports aptX

October 2011 Motorola Droid RAZR announced with
aptX

7. What can aptX do for Bluetooth?

With virtually no delay, a strong, robust connection, and providing
excellent channel density, aptX Live enables real-time digital
wireless audio in bandwidth constrained environments.

aptX Live audio compression technology enables developers of
equipment such as wireless microphones, wireless intercom, inear monitoring devices and talkback links to achieve maximum
efficiency from the available spectrum. This innovative coding
technique delivers the professional acoustic quality and real-time
operation of analog wireless devices within the bandwidth
limitations of multi-channel digital operation.

8. Benefits of aptX

The aptX Live audio codec is also ideal for the delivery of multi-channel
audio - from mono to surround sound - in real-time over IP networks.
Leveraging professional expertise gained in the pro-audio and broadcast
industries aptX Live audio compression technology can be utilized to
realize low-latency distribution of high quality audio for online multiplayer gaming. For the ultimate immersive audio experience in online
gaming the delay between users needs to be reduced.

aptX Live has the lowest delay of any professional audio codec available
and so can ensure seamless audio-video synchronization.

Outstanding CD audio quality

Extremely low audio coding delay

Strong resilience and robust to bit errors

Optimized implementation for low power DSP

9. Outstanding Features



Low delay - 1.9ms (aptX)
algorithm latency +
Bluetooth delay (approx
30ms)
High quality - 92dB for
16-bit audio
“Non-destructive” nature
maintains integrity of 3D /
matrix algorithms
Lower latency for games and “lip sync” applications
 Video Lip Sync requires a latency below 40ms
 As aptX is a sample based codec, low latency can be achieved
through efficient population of packets while retaining
transmission robustness 32 ms latency from the Audio Adapter
 Requires CSR devices at both ends of the link


10. Spec and Applications

The aptX Live audio codec can deliver a single
channel of 24bit, 48kHz audio in 120kbps
with a codec latency of less than 1.9ms.

The framework of aptX Live ensures a high
resilience to random bit errors. Additional
techniques employed within aptX Live will
also reduce the significance of these errors
and the magnitude of the effect of certain
signals.

The aptX Live decoder has a signal input from
the RF link which can aid the management of
bit errors or problems with the link.
Applications :

Digital wireless microphones

Wireless speaker

Wireless headphone

Car multimedia console

Intercom / 2-way push to talk

Talkback applications

Audio for Video Broadcast contribution

Multi-player online gaming
Specification:
 Compression ratio: Scalable up to
8:1 (16-bit) or 12:1 (24-bit)
 Audio format: 16-bit or 24-bit
 Data rates: 120kbps
(16bit,48kHz,6:4:1 compression) is
optimal setting
 Frequency response: 10Hz to 24kHz
 Delay: <1.89ms @ Fs 48KHz
 Dynamic range: 16-bit: >92dB, 24bit: >120dB
 THD+N: -88dB (16-bit), 90dB (24-bit)
at 4:1 compression and 48 kHz Fs
 Bit error resilience: Up to 1:10,000
