In this paper, we describe various application scenarios for archive management, broadcast/stream analysis, media search and media forensics which require the detection and accurate localization of unknown partial audio matches within items and datas

This work proposes a method for source device identification from speech recordings that applies neural-network-based denoising, to mitigate the impact of counter-forensics attacks using noise injection. The method is evaluated by comparing the impac

In this paper, we propose the use of denoising for microphone classification, to enable its usage for several key application domains that involve noisy conditions. We describe the proposed analysis pipeline and the baseline algorithm for microphone

In this paper we present a novel approach for environment classification for speech recordings, which does not require the selection of decaying reverberation tails. It is based on a multi-band RT60 analysis of blind channel estimates and achieves an

Within recent years, several applications have emerged which require detection and accurate localization of unknown partial audio matches within a dataset. This requirement cannot be adequately addressed with state-of-the-art matching approaches base

Video surveillance is becoming increasingly common, but raises serious questions related to data confidentiality and privacy issues. In order to address these issues, several approaches for selective video encryption have been proposed within recent

The following paper presents our work on audio phylogeny with a focus on two application scenarios: audiovisual (A/V) archives and tampering detection. Starting from a set of near-duplicate audio files, our goal is to determine the processing history

In this paper, we present a new algorithm for open-set microphone classification, which is based on a pre-existing blind channel estimation approach. The proposed method achieves a Rand index above 93% for AAC, MP3 and PCM-encoded recordings from eig

In this paper, we propose a new method for AAC encoding detection and bitrate estimation from PCM material. The algorithm is based on a Convolutional Neural Network that can distinguish between eight different bitrates. It achieves an average accurac
