TestHiFi is one app with two distinct measurements,
test your audio system and
test at listening position including room influence.
Test your audio system
The first and only app that allows you to test
the HiFi capability of your audio system
test audio system carousel
TEST MENU
connect to audio system, adjust loudness level, test area
TEST GUIDE
step-by-step guide how to test the system
ADJUST LEVEL
adjust to necessary loudness of the test signal
TEST POSITION 1 (3)
first of three test positions to test the system
TestHiFi RESULT
seven criteria test result with an overall rating and one for a each criteria
FIRST DETAILED RESULT
new graphical output for frequency response
New measurement at listening position
The first and only app that allows you to test
the HiFi capability at your listening position including room influences
Test listening Position carousel
TEST MENU SCREEN
connect to audio system, adjust loudness level, test area
TEST GUIDE
step-by-step guide how to test the system
ADJUST LEVEL
adjust to necessary loudness of the test signal
TEST POSITION 1 (3)
first of three test positions to test at listening position
TestHiFi RESULT

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).

Why TestHiFi? Non-technically interested friends used to ask why we do such a thing as the TestHiFi app.I could have answered with the words of another friend, who, when asked “why” about his super-elaborate tube […]
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 […]
