Steps Better Audio
Look (and Listen) beyond numbers.
SNR, THD+N sample rate provide reasonable start when selecting components power your design. However great audio about numbers sheet paper, about sound quality listening experience. Listen DAC, codec we'll that you'll love sound over sound competing products!
Good sound system, component. Look costs.
Some audio converters have jitter tolerance, requiring extra money spent clock circuits maintain performance. some best jitter tolerance business, consistent, great performance assured.
Competing parts require more complex filters conversion from current output high-frequency clocks used digital systems (CPU/system voltage output. clocks, memory clocks, etc.) cause problems analog DACs voltage audio domain. Separate ground power planes, short power output devices, simplifying traces judicious routing clock signals play part getting best performance from your design. have external circuitry. AKM's superior outquestions, Application Engineers happy review of-band noise your design help find problem areas. Here performance pointers help started with audio: eliminates complex multi-pole filters, Isolate analog digital ground planes. relying instead Place small bypass capacitors close chip simple twopossible pole designs. place inductors power supply lines, these restrict flow current chip reduce performance.
Good layout crucial great audio.
Group Delay Deviation: It's Phase Issue.
Group delay deviation relates chip's architecture affects signals that travel through Group delay deviation comes from using less-expensive filters inputs outputs DAC's internal architecture. These filters cause frequency dependent time/phase shifts. This means that sine wave will through device faster than 5KHz signal, resulting phase shift between these signals. multichannel audio, phase relationship different frequencies crucial providing spatial cues. DACs converters phase-accurate filters. This means that they respond predictably accurately, regardless input frequency sample rate. result better sound, better imaging superior performance.

Consistent performance across sample rates.
Filters should scale with sampling frequency. Period. using sample rates, like 8KHz 16KHz, non-scaling filters place extra noise audio spectrum. This reduces performance requires designer switch between external filters. DACs ADCs feature switched-capacitor technology, allowing on-chip analog filters scale with sample rate. This reduces external circuitry ensures superior sound.
Does your
Well, ours (sort of). see, when saturate inputs converters, digital output "pegged" maximum value, mater much exceed input maximums. Some parts "wrap around" negative full-scale (ouch!) begin re-incrementing. This forces system designer have compensate this wrap around either with expensive input circuit through DSP/CPU programming. AKM's approach simple, valid predicable behavior.)
Look past 20KHz response when evaluating sample rates.
Silence golden, noise.
What's point supporting high sample rates only looking energy from 20Hz 20KHz. Instruments like cymbals horns have harmonic content well past 20KHz. When test audio parts high sample rates, AES17 A-weighted filters what happening "in-band". lack noise this extended audio band will provide complete picture AKM's audio excellence!
Spurious noises. Sparkle codes. Spikes. Non-linearity. Periodic aberattions. Call what will. Whether converter converting not, unwanted tones unacceptable. With AKM, only time you'll hear) these objectionable signals well, never. Instead you'll truly random noise floor without specific tones spikes. This result superior technology careful design. With AKM, you'll crank signal noise.

After data collected, digital filter digital notch filter 16kHz applied. resultant spikes graph show non-linearity sparkle codes caused errant data.
Watch Your Power Supply.
Noise performance killer. Make sure that your power supply clean strong. This will improve audio performance throughout your system. possible, high-quality dedicated regulators with (converters need fast access current) high PSRR (Power Supply Rejection Ratio).

Automatic Level Control (ALC) found many codecs ADCs. located between analog preamp maintains incoming signal constant level. AKM's provides control Level, Time, Step Attenuation. Level threshold value above which initiated. Time amount time that signal must spend above threshold before starts. Step allows instantaneously "step" clipped value down Attenuation value wait until zero-crossing point reached prior making adjustments. Attenuation allows attenuate per-sample basis until signal level reduced below Threshold.

Class amplifiers pulse-width modulation (PWM) generate energy drive external loudspeakers. Since digital technology, possible have pure digital signal path from source (CD, DVD) speaker. image left shows analog sine wave represented using techniques. Most Class technologies result unacceptable THD+N (distortion) limitations PWM. developed technique that improves both dynamic range THD+N digital amplifiers. AKM's Class Technology offers Class performance with Class efficiency. input Class Amplifier digital, analog. Unlike other solutions that voltage levels modulation, AKM's Class products utilize multi-reference E-Bridge technology represent signal that transmitted speaker. This ability this intermediate voltage level interpolate input signal results improved dynamic range with less distortion. sounds better fewer issues than other offerings.
