Identification and verification of the location in which a recording was made are important yet understudied topics in audio forensics. The recently introduced concept of ‘roomprints’ provides some first steps towards tackling these tasks. A roomprint is defined as a quantifiable description of an acoustic environment which can be measured under controlled conditions and estimated from a monophonic recording made in that space. The various types of information which could be included in a roomprint are reviewed based on their expected reliability and the feasibility of extracting them from a recording. Frequency-dependent reverberation time is identified as a particularly promising feature in both regards. A room identification experiment was conducted using room impulse responses from 22 rooms. Depending on the frequency resolution and lower frequency extent of the roomprint identification rates of up to 97% were achieved.
