Phase refers to the variation in phase across the bandwidth of the filter. Antialiasing is a strategy to detect and filter out aliased signal components, but there is the potential to reject some of the signal too. Ideally, aliasing can be prevented by filtering out such frequencies before the audio is sampled. This is the same thing as a beat frequency in AM radio. Aliasing refers to the phenomenon in which sampled signals with frequency components greater than the nyquist frequency may sneak through as the difference between the actual frequency and the Nyquist frequency. The only limitation on that is the length of the filter, but longer filters result in a lag between the input and output signals, and require more processing power. The Nyquist frequency is the maximum hypothetical frequency of the audio signal that can be encoded at a given sample rate.ĭigital filters can be designed to mimic an ideal frequency response curve, which is flat right up to the Nyquist frequency, and zero above it. The drawback is that it introduces a degree of quantization error, which can result in distortion. The advantage of upsampling is that it increases the Nyquist frequency. Upsampling increases the sample rate of the data stream. I have no idea which method or methods SoX uses. There are also more sophisticated methods of upsampling that might be used. For example, upsampling can be done in a number of ways, including linear quadratic or parabolic interpolation. SoX is just an open source tool for digital audio signal processing. ![]() That being said, it would be nice to know some of the cause and effect of changing these settings given the understandable uniqueness of each of our systems and their strengths and weaknesses and how these might be better adjusted within these program settings. ![]() Use the default volume settings with exaSound DACs. By default Audirvana is setup for bit-perfect playback. If you haven’t done so, configure your Audirvana library. If you are using a third party DAC, select the appropriate values for it. The screenshot below shows the values used with exaSound DACs. ![]() If you haven’t done so, you can select the Preferred Audio Device by clicking the Change button. For more advanced users the best way to configure Audirvana for use with PlayPoint Players is to use the Preferences window. Browse around the Audirvana library to familiarize yourself with the user interface and play some music. You can control the volume from the PlayPoint touch-screen and from Audirvana. Make sure the PlayPoint volume level is safe. This step concludes the basic Audirvana setup. From the drop-down on the first screen select your PlayPoint as a playback device and click Next.įollow the instructions on the second wizard screen to configure the Audirvana music library. The first time you start Audirvana you will see the Setup Wizard. Note that there should be only one network connection between them, otherwise the UPnP connection may not work. You need to have a working PlayPoint player connected on the same network with the computer running Audirvana Plus 3. You can evaluate it for free for 15 days. Audirvana’s SysOptimizer configures your Mac for optimal audio processing.ĭownload and install the latest version of Audirvana Plus 3 from Audirvana. Wide range of Audio Unit effect plugins available on the market can be used to make equalization, room acoustics correction and spatialization for listening with headphones. Audirvana Plus offers to PlayPoint users an array of advanced audio processing options. Audirvana Plus offers convenient library manager and remote control app for iPads and iPhones. The user interface is stylish and simple to use. Home – Audirvana.MQA stops output MacOS 10/ – Tidal – Audirvana
