Abstract (in Japanese) (See Japanese page) 
(in English) This study addresses device-specific distortion observed in recorded
audio, to identify a built-in system-on-a-chip (SoC) in a portable
device. A swept sinusoidal signal is emitted from a loudspeaker and
is recorded by the portable devices. The three types of distortion
was observed by spectral analysis of the recorded signals. They are
the folded components at frequencies symmetrical across 4 kHz and 8
kHz of the signal component, non-harmonic and non-subharmonic
distortion components whose frequencies are 4 kHz below and
multiples of 4 kHz above the signal frequency, and mixed
non-subharmonics and folded components in the low-frequency
region. They are also observed using the correlation matrix on
temporal amplitude variations among frequencies derived from the
recorded speech signals and their perceptually compressed signals.
The folded distortions may be caused by signal processing of an auto gain control.
