| Best Cable Option: Streamer to DAC Again, any signal that is amplitude modulated will have sidebands. Organ note played will show single frequency on FFT, but interrupted 10 times a second will show root frequency and sidebands spaced 10Hz apart. I have to agree with you, that f... | |
| Best Cable Option: Streamer to DAC Any percussion instrument is an "continuous"No, it is not. If you record drum roll it will show individual bursts with silence in between. The signal is analog, it is continuous.Analog and continuous are two different terms. When you strike drum o... | |
| Best Cable Option: Streamer to DAC @cleeds instead "First two sidebands (21.9kHz and 22kHz) will have already very small amplitude and the rest of them can be ignored."it should say:"First two sidebands (21.9kHz and 22.1kHz) will have already very small amplitude and the rest of th... | |
| Best Cable Option: Streamer to DAC papafrgog, rate of incoming signal and rate of D/A conversion have to be synchronized. With async USB computer sends bunch of samples (frames) at certain rate (usually 1 kHz). DAC receives such frame and places it into buffer. Dac signals back... | |
| Best Cable Option: Streamer to DAC @cleeds It is likely that harmonics of 22kHz come from percussion instruments, that are not continuous by nature. 100Hz (drum roll) will give you (modulated) 22kHz with bunch of sidebands spaced 100Hz apart. First two sidebands (21.9kHz and 22kH... | |
| Best Cable Option: Streamer to DAC Nyquist applies only to continuous waves, so intermittent (music) 22kHz signal would have sidebands that may encroach on the 1/2 sampling frequency limit. It is remotely possible, but amplitudes of folded signals will be extremely small (as are 22... | |
| Capacitor upgrade jargon definitions "Poly" just means synthetic polymer. Film or Foil? Foil capacitors are made with metal foils (usually aluminium) separated by layer of dielectric while Film capacitors are made with metallized layers on dielectric films. Film capacitors are sma... | |
| What is an easy way to convert wav files to Flac? Try freac.org - free and easy to uses converter. You can use it as batch converter. I use it to convert ALAC to AAC (for phone and car). | |
| Bi-wiring using different cables Biwiring works with some speakers and has little to no effect with others. It might be related to Xover design. Some speaker makers don't believe in biwiring and make speakers with just one set of connectors. My speakers have three sets of bind... | |
| De-emphasis in DAC AFAIK, the sole purpose of deemphasis was to reduce tape noise in analog recordings - almost never used today, since most of recordings are digital. CD players have deemphasis built in and engage it automatically (CD contains deemphasis bit). | |
| Class H vs nCore for multi channel to match Class AB front stage. Class H means only, that supply rails switch between lower and higher voltage, based on the amplitude of the input signal, in order to lower power dissipation. Amplifier still operates in class AB. There might be some sonic penalty in class H, but... | |
| Coax Digital Out -> XLR Digital Input cable? XLR is a connector type, while AES/EBU (now known as AES3) is the name of digital standard (IEC 60958 type I) that uses 110ohm cable and XLR connector. | |
| Coax Digital Out -> XLR Digital Input cable? You need conversion device. S/Pdif and AES3 (balanced) have different input and output levels and also different characteristic impedance. One is single ended while the other is differential.In the past I used Canare transformer, but it is limite... | |
| Paralleled Transistors Using multiple bipolar transistors allows not only to distribute temperature between them, but also to lower their collector current. It improves linearity since current gain of transistor drops at larger collector currents (beta droop). Putting t... | |
| All about streaming They were open to this option in 2017, but looks like it is still not available. Tidal has HiFi option for "Master Quality" uncompressed music, but it doesn't cover all albums - only “Master Quality Authenticated Albums”. |
