HD Audio in Mobile Phones: HD Voice

9 © 2010 Wolfson Microelectronics plc June 2010

HD Voice in Mobile PhonesVoice calls using W-AMR encoding, compliant to 3GPP acoustic quality recommendation, and supporting noise cancellation, acoustic echo cancellation and other audio enhancements

High profile launches coming from Orange and others

Translation:

Mobile phone calls that sound as good or better than landline calls taken in a quiet room

Over half of the UK’s over 60s have age-related hearing loss(RNID)

Some are less tech savvy than those in younger generations

Almost all consume media as entertainment

Focus on Noise Cancellation: Two Types

13 © 2010 Wolfson Microelectronics plc June 2010

Tx NC

Transmit Noise CancellationReduces the noise when you talk

Rx ANC

Receive Ambient Noise CancellationReduces the noise when you listen

Wolfson ANC – What it Does

14 © 2010 Wolfson Microelectronics plc June 2010

1. Caller speech volume through handset speaker

2. Background noise drowns out the handset speaker – you can’t hear the caller

3. Wolfson ANC lowers the background noise so the speech can be heard clearly

• Monitors the incoming signal

• Creates a new signal that is equal in amplitude with the opposite phase

• Mixes the new signal with the incoming signal
