For millions of consumers worldwide, having a high-quality, high-fidelity music listening experience still matters in the digital era. Cirrus Logic believes that true hi-fi playback should reproduce audio that is as close to the original sound as possible. Hi-fi audio isn’t just about specifications. It’s more about how it should sound – alive, warm, clear and distortion free. Everything we do in the design of our audio products is done to ensure we don’t interfere with the audio experience. That amazing sound is not only captured, it's delivered.


High-Fidelity Audio Legacy

For nearly three decades, Cirrus Logic has built its reputation as audio IC experts. In the early 1990s, through the acquisition of Crystal Semiconductor, the company pioneered the creation of audio converters that helped to spark the digital audio revolution in professional audio and consumer home theater. Cirrus Logic's innovation continues today, with some of the industry's best engineers developing integrated circuits, embedded software and DSP algorithms that drive new generations of high-fidelity products.


Hi-Fi DACs and Headphone Amplifier Design

The design architecture of an audio IC is key to ensuring the quality of the original sound is reproduced as cleanly as possible. Cirrus Logic high-fidelity DACs are designed from the ground up to make a noticeable difference to the listener. Careful filter design and noise robustness ensure the desired audio elements are retained, but without the unwanted effects of digital processing and system design. The same principles apply in headphone amplifier design – if the design of the headphone ‘colors’ or changes the sound of the audio then it will impact the true recreation of the original source recording. Cirrus Logic takes great care in making sure that all our DACs and headphone amplifier designs deliver audio quality as true to the original source as possible.




Advanced Hi-Fi Filters

"Pre-ringing" is an artificial artifact introduced by digital processing that causes some sounds to be introduced before the real sound occurs. This means the audio isn’t as clear or as crisp as it should be. Cirrus Logic has created a number of advanced hi-fi digital filters that can eliminate these effects of the digital world and deliver natural audio sound as it is meant to be heard. Originally created for our highest performance DACs and used in pro-audio systems, these same filters are now available in Cirrus Logic mobile products, which means smartphones, tablets and wearable products can benefit from natural sound too.


Cirrus Logic Hi-Fi Audio for Mobile Devices

With mobile devices and streaming music services now beginning to offer an abundance of high-quality, lossless digital audio content, high-quality audio components such as smart codecs, DACs and headphone amplifiers make all the difference to the user's audio experience. If you’re listening to your favorite Pink Floyd single and it sounds like it was recorded in an underwater cavern, you should upgrade to a device featuring audio components from the audio experts at Cirrus Logic.



Home Stereo System in Your Pocket

What’s our secret? We use a combination of multiple technologies unique to Cirrus Logic that monitor the playback and quickly adjust power levels to match the music, which uses less power. OEMs rely on Cirrus Logic smart codecs to deliver premium audio quality and ultra low power simultaneously — neither is sacrificed!




MasterHIFI and SmartHIFI

MasterHIFI describes our highest-standard audio converters – DACs, ADCs and codecs offering supreme performance. SmartHIFI products deliver hi-fi audio quality, but have one or more low power audio DSP cores available for low power audio processing. Both MasterHIFI and SmartHIFI products from Cirrus Logic represent the highest standards and industry performance for pristine audio quality.
