Real-time large-scale arithmetic processing via multi-core technology
The AK7709VQ’s 7,000MIPS processing capability and 2.75 MB of built-in memory 2.75MB enable real-time high-resolution audio processing for automotive speaker arrays featuring 30+ channels, enabling a quiet cabin with immersive, incredibly detailed audio. This DSP is also well-suited for high sample rate multi-microphone voice processing.
Innovative software for in-cabin audio and voice processing
AKM’s proprietary sound design audio-processing suite, designed for the AK7709’s four AK77 cores, supports expert tuning that delivers a listening experience as if you were there for the original musical performance. Additionally, the two integrated HiFi 4 DSP cores support a wide range of third-party software. AKM also offers a variety of original software products, including hands-free and in-car communication suites, which have been developed over more than 20 years of experience with audio for vehicle interiors.
Audio hub function that facilitates total system design
The built-in audio hub function, which includes 20 channels of asynchronous hardware SRC, supports flexible digital input/output to and from a multitude of digital sources and endpoints, such as music playback and telephone calls.
Acoustic Design Solution
AKM’s acoustic design solution is carried out under the supervision of audio professionals who spend every day working with and learning from the audio meisters who have continued to meet the rigorous demands of the high-end audio industry.
Audio & Voice DSPs
Our automotive audio DSPs are equipped with multiple cores for total of more than 7000 MIPS of computing power and up to 152-channel interfaces that can process complex algorithms simultaneously.
This flexibility allows these devices to adapt to different audio systems from customer to customer. Our DSP hardware is capable of efficiently tuning not only the quantified acoustic characteristics, but also the subtle differences in sound quality that can be felt by the body.
Audio Algorithms
Algorithms are available to compensate for major user-sensitive parameters. By using these algorithms, the sound position is clearer, the sound space is wider and more balanced, the bass is more powerful, and the sound space in the image is reproduced.
By using these algorithms, you can reproduce the sound space of an image, where the sound position is clearer, the sound space is wider and more balanced, and the bass is stronger.
Professional Tuning
AKM’s tuning technology is based on the theory and experience that only a company with decades of success and high regard in the HiFi industry can offer. Meticulous tuning by audio professionals delivers an automotive listening experience that delights the audience and captivates the senses.
Engine Sound Creator
With the spread of EV, the absence of regular engines makes the cabin quieter. That means that the sound of your favorite engine will no longer be heard for those who are interested in cars. The engine sound creator of AKM allows you to select the “engine noise” of the EV you were driving. For example, this can be V8 or V12 cylinder noise. The engine sound creator generates engine sounds through real-time computation by DSP and does not use sampled sounds. This makes it possible to experience a very realistic sound depending on the degree that the accelerator pedal is pressed.
With the demonstration video, you can experience everything from the sound of a nominal car to the sound of a car in the future.
Product Q&A
Q Is external memory required?
The program downloaded by DSP must be stored in the internal memory of SoC or external Flash memory.
QWhat engine sounds can ESC create?
Then, tool that allows the user to tune using CAN information is provided to the user.
QPlease provide commercial distribution information in each area.
