Introducing Lossless Audio over Wireless Bluetooth
Experience sound as if listening live
Our approach
Alta Semiconductor builds Bluetooth audio chips focused on high-fidelity sound for audio products, wireless accessories, and gaming markets.
We use powerful technology to deliver ultra-low latency and exceptionally clear sound over Bluetooth. Our chips replace wired high-fidelity accessories that can cost thousands of dollars, cutting the cable for greater convenience and giving stunning audio performance to all.
Sound quality is the most critical driver when purchasing audio accessories
Alta Semiconductor delivers a true wireless stereo (TWS) experience with lossless audio for Bluetooth audio accessories.
Bluetooth 5.3 with LE Audio
The latest version of Bluetooth technology is 5.3, and enhances connectivity, reliability, security, design flexibility, and power efficiency. All of this translates into improved user experience. The LC3 audio codec is a new optional feature for the Bluetooth 5.2 and 5.3 chips, though few chips currently offer this addition. Alta Semiconductor builds Bluetooth 5.3 chips with LC3 Audio, layered on top with additional proprietary technology for active noise cancellation (ANC), spatial audio, and harmonic equalization for the most full and accurate sound.
Audio Codec
Codecs are algorithms that compress audio data for easier and faster transmission. They determine how the sound transmits from the source device to the audio accessory. The newest Bluetooth codec is called LC3, which among other characteristics, gives higher quality sound at the same bit rates or even better audio quality at lower bit rates. It replaces the SBC codec found in older Bluetooth chips or even 5.2 and 5.3 chips without LE Audio. SBC transferred audio data with significant data loss, had high latency, and poor to average audio quality. SBC is incapable of delivering true wireless stereo performance. Most methods of audio compression lose part of the data from the original source file; however our codecs can deliver audio that is nearly identical to the original recorded sound.
Sound Technology
Our chips offer the Bluetooth LC3 audio codec and additional proprietary algorithms to immerse yourself in music and movies. Our Bluetooth 5.3 chip restores digital audio data for more dynamic and detailed sound, 3D spatial audio, and clear crisp calls. Audio is smoother, can work even in congested radio environments, and can be transferred to multiple devices at the same time. With ultra-low latency, there is no lag between what you see on the screen and what you hear— meaning that with our chips, gaming accessories can finally be wireless.
