The brain can accurately detect minute variances in sound as it travels at different distances to each ear and delays of microseconds are significant enough to perceive a shift in sound location. These subtle nuances are introduced into an audio recording to recreate the effect of stereo and surround sound.
Wireless speakers require very tight synchronization between each device in order to faithfully reproduce the dynamics of the audio environment. The human ear can typically detect a deviation of between 40-50 microseconds between speakers, but using StreamSync Caskeid achieves less than 5 microseconds.
This means that listeners to speakers based on the Caskeid platform with StreamSync technology can hear each individual instrument and vocal performance as it was created in the studio with no drift or shift in the stereo landscape.
Synchronization at this level is a non-trivial problem, often impacted by unreliable network or unfavourable environmental conditions. The threat of instability can really impact the listening experience especially when listening to stereo or surround sound.
Other wireless speakers on the market typically deliver poor audio synchronization, which can create echo or dissonance that the listeners perceive as an imprecision in clarity. Tests with competitive systems showed a maximum deviation of 1800 microseconds which meant that stereo reproduction is impossible as the listener will experience the sound field moving between speakers. The closest match to Caskeid delivered 180 microsecond deviation between speakers but required an average of 20 minutes to achieve optimum synchronization. Caskeid’s StreamSync technology, under identical conditions, is eight times more accurate from the outset and synchronized immediately every time.
Digital audio systems can suffer from latency. This refers to a short period of delay (usually measured in milliseconds) between when an audio signal enters and when it emerges from a system. StreamXprs ensures system latency between a group of Caskeid speakers is kept below 30 mSec.
The following audio clip helps demonstrate the difference between Caskeid StreamSync and competitive wireless solutions. We recommend listening to it using stereo headphones. The first version of the audio represents Caskeid, with tightly synchronized StreamSync audio.
