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 […]
Flaws in audio systems – stereo capability
Text to speech – TestHiFi blog: Flaws in audio systems – stereo capability Theory explanation Systems with one channel only or summed up left and right channel. Such systems are incapable of providing stereo […]
Phase and Time 3
Text to speech – TestHiFi blog: Phase and Time 3 Phase and Time – Time Domain Response, Step Response In my first blog „Phase and Time 1“ I focused on amplitude and phase shown as […]
Flaws in audio systems – aurally weighted intermodulation disconsonance
Text to speech – TestHiFi blog: Flaws in audio systems – aurally weighted intermodulation disconsonance Theory explanation Frequencies with higher level of upper order harmonic distortion compared to level of lower order harmonic distortion […]
Phase and Time 2
Text to speech – TestHiFi blog: Phase and Time 2 The system that shouldn’t work well – phase and time completely ignored! Last time I wrote about phase and time issues of loudspeakers. A result […]
Flaws in audio systems – loudness at intermodulation distortion limit
Text to speech – TestHiFi blog: Flaws in audio systems – loudness at intermodulation distortion limit Theory explanation Accumulated level of all distortions compared to level of multiple low respectively high frequency test tones. Critical […]
Phase and Time 1
Listen to the blog: Phase and Time 1 While certain crossover configurations let tweeter (HF) and woofer (LF) radiate in phase with each other, this does not mean they radiate at the same time. Motivated by […]
