Tests the HiFi capability of a music system

TestHiFi is one app with two distinct measurements,

test your audio system and

test at listening position including room influence.

tests your sound system

TestHiFi SOUND TESTS

NEW!!! FREE!!! iOS and Android NEW!!! FREE!!!

TestHiFi App is now available on iOS and Android

simple sound quality measurement and rating

for professional use also

second complete new measurement

measure at your listening position

measure the combination of audio system and room influence

WYSIWYG – What You See Is What You Get

WYSIWYG for audio – this demonstrates what you get to hear

WYSIWYG for audio – rooms can degrade sound from best systems

in addition to the audio system measurement

limits unwanted room influences to the greatest possible extent

each measurement measures 7 industry standard criteria

each measurement provides one overall rating and one for each criteria

both measure in three positions average

Criteria measurement audio system

TestHiFi criterion: frequency response amplitude drop

identified frequencies with significantly lower volume, such as early upper or lower frequency decline or dips

TestHiFi criterion: frequency response amplitude peaks

identified frequencies with significantly higher volume, e.g. steep or smooth amplitude peaks

TestHiFi criterion: loudness at harmonic distortion limit

lower frequencies at which a minimum volume cannot be achieved within acceptable distortion limits

TestHiFi criterion: intermodulation distortion low frequency

accumulated level of distortions, consisting of harmonic, sub-harmonic and intermodulation distortions, inappropriately high compared to level of multiple low frequency test tones

TestHiFi criterion: intermodulation distortion high frequency

accumulated level of distortions, consisting of harmonic, sub-harmonic and intermodulation distortions, inappropriately high compared to level of multiple high frequency test tones

TestHiFi criterion: aurally weighted intermodulation disconsonance

frequencies with higher level of upper order harmonic distortion components compared to level of lower order harmonic distortions components are disconsonant with human hearing

TestHiFi criterion: stereo capability

potential systems with one channel only or summed up left and right channel

Criteria measurement listening position

TestHiFi criterion: frequency response left and right channel

identified frequencies with significant volume variance 

lower: such as early upper or lower frequency decline or dips

higher: such as large or smooth amplitude peaks

TestHiFi criterion: frequency domain channel correlation

identified differences between stereo channels that disturb the stereo image

TestHiFi criterion: transmission signal elongation

Elongation occurs mostly with wireless connection, in the early part of the signal and continuously decreases towards the end of the signal. Best test results should be achieved with wired connection.

TestHiFi criterion: frequency group time coherence

identified incorrect time delay between higher, middle or lower frequencies, i.e. too early or too late mids or basses

TestHiFi criterion: transmission signal elongation:

elongation occurs mostly in the early part of the signal and decreases over time; high elongation with steep decrease eliminate for the possibility to measure the TestHiFi criteria related to time coherence and polarity

TestHiFi criterion: phase coherence 

identified phase differences between mid, lower mid or bass frequencies

TestHiFi criterion: polarity variation

Identified inverted polarity between left and right channel

First test app with instantaneous results

A HiFi music system is expected to replay recorded sound without unpleasant distortions and with full quality. HiFi sound, provided by a HiFi music system, should arrive at listening position without being compromised by room reflections or ambience influences.

TestHifi sends a complex, but short, test signal through the sound system and analyzes the acoustical output in three microphone relevant positions either infant of the audio system or at listening position. TestHiFi provides instantaneously a final test result and the rating (red, amber, green).

Frequency Response (Amplitude versa Frequency)

Between reasonably designed music systems (and setups), the frequency response is the most important characteristicum.The new version of TestHiFi now includes the (paid) option to display a frequency response. Measuring amplitude versa frequency shows if […]

Digitalization – how far can it go?

Just recently I came across a new album, composed and played by AI. Also I found quite an interesting theses on the digitalization influence to the music business. This blog cites abstracts of those. Music […]
