cMelGAN: An Efficient Conditional Generative Model Based on Mel Spectrograms

open access: yesCoRR, 2022
Analysing music in the field of machine learning is a very difficult problem with numerous constraints to consider. The nature of audio data, with its very high dimensionality and widely varying scales of structure, is one of the primary reasons why it is so difficult to model.

CycleGAN-VC3: Examining and Improving CycleGAN-VCs for Mel-Spectrogram Conversion [PDF]

open access: yesInterspeech 2020, 2020
Non-parallel voice conversion (VC) is a technique for learning mappings between source and target speeches without using a parallel corpus. Recently, cycle-consistent adversarial network (CycleGAN)-VC and CycleGAN-VC2 have shown promising results regarding this problem and have been widely used as benchmark methods.

An investigation of the reconstruction capacity of stacked convolutional autoencoders for log-mel-spectrograms [PDF]

open access: yes2022 16th International Conference on Signal-Image Technology & Internet-Based Systems (SITIS), 2022
In audio processing applications, the generation of expressive sounds based on high-level representations demonstrates a high demand. These representations can be used to manipulate the timbre and influence the synthesis of creative instrumental notes. Modern algorithms, such as neural networks, have inspired the development of expressive synthesizers ...

Mel-spectrogram features for acoustic vehicle detection and speed estimation

open access: yes2022 26th International Conference on Information Technology (IT), 2022
The paper addresses acoustic vehicle detection and speed estimation from single sensor measurements. We predict the vehicle's pass-by instant by minimizing clipped vehicle-to-microphone distance, which is predicted from the mel-spectrogram of input audio, in a supervised learning approach.
