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 […]
Flaws in audio systems – loudness at harmonic distortion limit
Text to speech – TestHiFi blog: Flaws in audio systems – loudness at harmonic distortion limit Theory explanation Systems that produce too many distortions especially when playing lower frequencies at higher amplitude levels. Some audio […]
Loudspeaker Phase Response
Text to speech – TestHiFi Blog: Loudspeaker Phase Response Loudspeakers usually radiate different frequencies with different phase. This is due to the drivers themselves, interaction with the cabinet, and the crossover. A basic example of phase […]
Flaws in audio systems – frequency response amplitude peaks
Text to speech – TestHiFi Blog: Flaws in audio systems – frequency response amplitude peaks Theory explanation Frequency response amplitude peaks: some frequencies are reproduced with higher level than others. An audio system accelerating some […]
Loudspeakers and Single Ended Tube Amplifiers
Text to speech – TestHiFi Blog: Loudspeakers and Single Ended Tube Amplifiers What are SETs? Short for Single Ended Tube, or more specific, Triode Amplifier. My favorite kind of amplification! The inherent problem of those […]
