Here, we have discussed various methods to detect tampering in audio signals. Method-I: Using Frame offsets The method to detect forgery in MP3 file is by checking the frame offset of the signals. Audio samples are divided into frames to encode, and after encoding process each frame has its own encoding. By breaking the frame grids of audio

Audio tampering detection via microphone classification. Abstract: In this paper, we present a new approach for audio tampering detection based on microphone classification. The underlying algorithm is based on a blind channel estimation, specifically designed for recordings from mobile devices. It is applied to detect a specific type of tampering, i.e., to …

To detect resampling in audio tampering, a new spectral measure, band-partitioning spectral smoothness (BPSS), is proposed to measure the degree of spectral fluctuation.
ESPRIT-Hilbert-Based Audio Tampering Detection With …

Abstract: Audio authentication is a critical task in multimedia forensics demanding robust methods to detect and identify tampered audio recordings. In this paper, a new technique to detect adulterations in audio recordings is proposed by exploiting abnormal variations in the electrical network frequency (ENF) signal eventually embedded in a questioned audio recording.

A different approach was explained by Lin & Kang (Lin & Kang, 2017), the detection of audio tampering was done by developing an effective detector for multiple types of audio forgeries. Based on the fact that tampering with an audio leads to anomalous variations of the underlying ENF signal, a wavelet filter to the extracted ENF
