Flaws in audio at listening position – frequency group time coherence
Theory explanation Time and phase coherence is a very complex topic, probably not yet fully researched which and how those issues directly influence or correlate to the subjective perceived sound quality. However, it is […]
Why isn’t time and phase a prominent topic in audio?
Stereo channel time and phase coherence Sound mixer or sound engineer proactively design the sound with in-phase or out-of-phase channels. More mono able sound, i.e. channels in-phase will sum-up in levels. Amplitudes of same frequencies […]
Time and phase coherence – live, MQA, playback, overall
This is a very complex topic. It is not fully researched which and how the issues directly influence or correlate to the subjective perceived sound quality. However the overall time and phase coherence influences the […]
Faint sounds of distortion
Did you ever hear the noise produced by an audio amplifier under measurement, with resitors instead of loudspeakers connected? There is a lot of buzz, and sometimes hum. If components in an audio circuit produce […]
Flaws in audio at listening position – stereo channel left and right level correlation
Theory explanation Stereo, a method of sound reproduction We described stereo effects to some extend already in the criteria stereo capability and Frequency response channel correlation. Stereo is a method of sound reproduction that […]
Digital HiFi Adventures – and Questions
Between 1990 and 2005 I worked with digital controllers for custom made horn systems in critical sound reinforcement situations. The convenience to have a variety of filters, delay and equalizing selected via a nice graphical […]
Flaws in audio at listening position – frequency response channel correlation
Text to speech – TestHiFi blog: Flaws in audio at listening position – frequency response channel correlation Theory explanation Frequency response channel correlation at listening position We described the frequency response amplitude level or […]
Flaws in audio at listening position – frequency response
Text to speech – TestHiFi blog: Flaws in audio at listening position – frequency response Theory explanation Frequency response amplitude drops or peaks at listening position Frequency response is used to describe the output […]
Listening Position Frequency Response
Text to speech – Listening Position Frequency Response Does measuring amplitude versa frequency (frequency response) at the listening position make sense? I wrote about measuring at the listening position before, and covered room influence etc […]
