It’s truly plug and play which is good for computer illiterate audiophiles.ĪirStream can deliver better streaming quality with EtherStream to get “fully energized” network packets with dedicated network circuit improvements before streaming into the air.
#Airstreamer password
You can enter your own WiFi name and password before ordering. Devices in AirStream, modem router/network switch, and wireless devices can communicate in the same network.Īfter plugging ethernet cable to AirStream’s blue port, you can join “AirStreamSerialNumber” with “fidelizer” as the password. You can hold WPS button to disable LED light to reduce noise in device too.Īccess point configuration will allow you to connect wireless devices to devices in previous network with the same configuration. AirStream can manage network configuration as plug and play access point without network issues. One of classical problems in network is having some devices not visible from WiFi due to different network configuration. And that allows tuning for highest fidelity audio possible after lots of trials and errors.
#Airstreamer upgrade
With high precision clock upgrade and technology to re-energize network packets from EtherStream, we can make WiFi streaming becoming much more resolving for the first time. Router is configured for low-latency audiophile streaming applications Components are soldered with high quality solder providing solid bass and dynamics Crystal clock is upgraded with high precision clock optimized for network application with noise reduction tweaks
Re-energize power supply with special tantalum capacitors to reducing noise and interference in processor chip effectively Upgrade Safety resistors with high power from Vishay Dale on DC input stage, power regulation stage, and isolation transformer stage Upgrade Capacitors with high capacitance and low impedance tuned in 3 different stages for optimal sonic performance It took a while to know how I should tune each stage correctly and to find out where I should emphasis on capacitor’s better specs or better sound. WiFi modulation is more sensitive than I initially thought.ĪirStream has 3 stages power supply capacitors to handle modules in different roles and areas. I thought AirStream can be done in a few weeks but it ended up taking over a year to complete. I spent about 2 years in tuning EtherStream to get neutral sound meeting my standards. Never compromise for the best wireless streaming This concept is what Fidelizer has been working on for years. Even if it’s wireless, if you can get the right data on the right time closer to zero jitter, you modulated data closer to ideal situation. In digital world, it’s all about data and timing. Can decode the same data but not on the exact timing with more jitter. It can work but may have more signal loss during transmission. So, having high noise level is like CD player having budget power supply grade.
#Airstreamer code
This process is similar to CD player sending pulse signal from laser drive to DAC and modulate pulse code signal. WiFi module will send and receive data through specified radio frequency and modulate signal from radio frequency into data. Noise in circuit can affect WiFi’s modulation and cause jitter With improved timing accuracy and reduced noise in circuit, WiFi module can perform modulation more precisely having improved focus and imaging with less frequency distortion thanks to high quality clock and technology applied in EtherStream. Consumer grade router with bare minimum timing accuracy in clock and internal noise level can affect WiFi transmission to have blurred imaging with frequency distortion. WiFi use radio frequency with fixed modulation rate in different channel. WiFi has modulation and also needs precision However, modification changed my perception about WiFi’s capabilities and here’s why. It’s just hard to see wireless can make big improvements like wired.
I must admit I didn’t have expect expectations for WiFi improvements to be high at first. Identifying problems in WiFi and solutions It has very good design based on flagship model with quad core processor for audio improvements. That’s how I started working on this “AirStream” project for over a year with ASUS RT-AC1300UHP model. Maybe I can apply modification as WiFi version of EtherStream. However, I still feel WiFi network lacks satisfying performance compared to wired connection with EtherStream directly. “There’s high fidelity audio in the air.”Īfter finishing EtherStream development, it has become core infrastructure of streaming services improvements chaining to WiFi router.
