BCM4330 Preliminary Data Sheet
Music and Audio
Section 6: Music and Audio
The BCM4330 provides superior total system current during music or audio playback and recording. To enable
these functions, several features of the device are combined to provide superior system power consumption.
MP3 Encoder
• ISO/IEC 11172-3 compliant
• Supports 32 kHz sampling frequencies only
• Encodes mono and stereo signals
MP3 Decoder
The MP3 decoder supports mono and stereo audio recording with the following specifications:
• Supports MPEG-1 Layer 3 decoding
• Output is fully bit compliant with MPEG-1 standard specification
• Supports sampling frequencies from 32 kHz to 48 kHz
• Minimum bit-rate supported 32 Kbps and maximum bit-rate supported 320 Kbps for Layer 3
AAC/AAC+ Decoder
Compliant to ISO/IEC 14496-3: 2004 specifications:
• MPEG-2, MPEG-4 AAC LC decoding up to level 2
• SBR tool, up to level 3
• Low power SBR tool
• Full support up to level 3 for the HE AAC profile
• Implicit and explicit SBR signaling mechanisms
• Mono and stereo channel streams decoding sampling frequencies from 8 kHz to 96 kHz only
• ADTS frame decoding
