Audio & Voice Processors

New Audio 32-bit Hi-Resolution DSP Core Solutions

AK7737 and AK7739 are AKMs first new DSP core architecture that maintain 32-bit audio word through the DSP.  These new DSPs use a F32.5 data format that enables a 32-bit mantissa with sign bit, a 5-bit exponent.  This revolutionary new architecture is more ideally suited for audio processing than the traditional IEEE 32-bit floating point processing.  The 32-bit mantissa maintains the audio signal more precisely within the audio signal level.  This can greatly increase the sound quality through the DSP processing.
