Audio & Voice DSPs
What makes AKM different ?
Safe & Comfortable Cabin
Automobiles are not only a means of transportation, but also a living space where people spend their time.
To ensure that this space is comfortable and safe at all times, Asahi Kasei Microdevices (AKM) has provided unique audio & voice processor products and software for more than 15 years.
Here, we introduce the backgrounds and reasons for the popularity of our products in this demanding automotive field.
Road Noise Cancellation technology is reducing the noise that is generated from road induced vibrations. This is performed by composied a secondary sound field using acceleration signals as inputs and processing these signals in real-time with low-latency computational efforts. AKM provides low-latency ADCs that enables fast signal transmission to the AKM DSPs that host the Silentium Road Noise Cancellation libraries. As a result, the total combined SW/HW system becomes a unique solution for low-latency automotive ANC (Active Noise Cancellation) applications.
Audio & Voice Processors
Improving Quality of Life with Voice technology
The AK7739VQ is a highly integrated digital signal processor, including a 24-bit stereo ADC with MIC gain amplifiers, a 24-bit stereo ADC with input selector, two 32-bit stereo DACs, 4 stereo & 4 monaural sample rate converters (SRCs) supporting the sampling frequency up to 192kHz, a DIT, two DSPs and a Sub DSP for Audio / HF process.
