Multitone testing is the foundation on which HST, Audio Precision’s High Speed Test Application for the 2700 series and ATS-2 audio analyzers is built. HST was featured earlier this year in the January issue of Audio.tst. As the name implies, a multitone stimulus signal consists of multiple sine waves (or tones) at different frequencies combined together.

Multi-tones can be used in an open-loop audio test where the analyzer does not have to sync up with the generator. This allows an audio signal to be tested over long distances, such as the internet or mobile phone. Standard multi-tone signals have evenly-spaced tones with equal amplitude; this, however, does not represent real-world test conditions.

MTD. Multi-tone noise floor (absolute, relative) MTON. MTD. Any nonlinear system such as a loudspeaker generates new spectral components which are not present in the stimulus. In addition to harmonics, the fundamental components interact with each other and generate difference- and summed-tone components in the output signal (intermodulation distortion) …

Distortion is -110db vs -140db. The multitone generator limits what can be measured. As opamps nowadays can reach down to -160db -170db distortion. Using multitone isn't helpful. Multitone is supplementary measurement to all other existing measurements. Like Sanskrit, M300 mkii have horrible multitone measurements but very good SINAD.

Multitone testing Hello Audioreview forum members, glad to be joining your number. ... and I'd just like to make the following observations: If a system is linear, a single test will prove the point. In theory! Obviously you're limited by noise and other extraneous problems of resolution, but if a sine wave goes in and comes out _completely_ ...
