Audio recordings microphones dataset (gun shot)
Description
Microphones recordings from the built-in microphone from 34 mobile phones (each equipped with a single microphone) stimulated by a gun shot sound. The recordings are in PCM format at 44.1 KHz. No SIM was inserted in the mobile phone and no personal data was recorded. The recording took place in a laboratory. The data set is composed by 800 repetitions of the recording based on the repetition of the gun shot sound for each microphone. The dataset is useful for studies on multi-factor authentication of mobile phones and fight against distribution of counterfeit electronic products. The data set is a three dimensional matrix with three dimensions: the first is the identifier of the phone, the second is the audio recording and the third is the repetition of the sound.
