Frequency-domain Source Identification and Manipulation in Stereo Mixes for Enhancement, Suppression and Re-panning Applications
نویسنده
چکیده
In this paper we describe a frequency-domain framework for source identification, separation and manipulation in stereo music recordings. Based on a simplified model of the stereo mix, we describe how a similarity measure between the Short-Time Fourier Transforms (STFT) of the input signals is used to identify time-frequency regions occupied by each source based on the panning coefficient assigned to it during the mix. Individual sources are identified and manipulated by clustering the time-frequency components with a given panning coefficient. After modification, an inverse STFT is used to synthesize a time-domain processed signal. We describe applications of the technique in source suppression, enhancement and re-panning.

Frequency-Dependent Amplitude Panning for the Stereophonic Image Enhancement of Audio Recorded Using Two Closely Spaced Microphones
In this paper, we propose a new frequency-dependent amplitude panning method for stereophonic image enhancement applied to a sound source recorded using two closely spaced omni-directional microphones. The ability to detect the direction of such a sound source is limited due to weak spatial information, such as the inter-channel time difference (ICTD) and inter-channel level difference (ICLD). ...
متن کاملA Novel Frequency Domain Linearly Constrained Minimum Variance Filter for Speech Enhancement
A reliable speech enhancement method is important for speech applications as a pre-processing step to improve their overall performance. In this paper, we propose a novel frequency domain method for single channel speech enhancement. Conventional frequency domain methods usually neglect the correlation between neighboring time-frequency components of the signals. In the proposed method, we take...
متن کاملStage- vs. channel-strip metaphor - comparing performance when adjusting volume and panning of a single channel in a stereo mix
This study compares the stage metaphor and the channel strip metaphor in terms of performance. Traditionally, music mixing consoles employ a channels strip control metaphor for adjusting parameters such as volume and panning of each track. An alternative control metaphor, the so-called stage metaphor lets the user adjust volume and panning by positioning tracks relative to a virtual listening p...

This letter proposes a novel nonlinear distortion for the unique identification of receiving room impulses in stereo acoustic echo cancellation when applying the frequency-domain adaptive filtering technique. This nonlinear distortion is effective in reducing the coherence between the two incoming audio channels and its influence on audio quality is inaudible. key words: acoustic echo cancellat...
