Bass Accompaniment Generation via Latent Diffusion

no code implementations2 Feb 2024 Marco Pasini, Maarten Grachten, Stefan Lattner

At the core of our method are audio autoencoders that efficiently compress audio waveform samples into invertible latent representations, and a conditional latent diffusion model that takes as input the latent encoding of a mix and generates the latent encoding of a corresponding stem.

Exploring Sampling Techniques for Generating Melodies with a Transformer Language Model

no code implementations18 Aug 2023 Mathias Rose Bjare, Stefan Lattner, Gerhard Widmer

To accomplish this, we train a high-capacity transformer model on a vast collection of highly-structured Irish folk melodies and analyze the musical qualities of the samples generated using distribution truncation sampling techniques.

On the Typicality of Musical Sequences

no code implementations23 Nov 2022 Mathias Rose Bjare, Stefan Lattner

It has been shown in a recent publication that words in human-produced English language tend to have an information content close to the conditional entropy.

SampleMatch: Drum Sample Retrieval by Musical Context

no code implementations1 Aug 2022 Stefan Lattner

Artists must use their aesthetic judgement to assess whether a given drum sample fits the current musical context.

Contrastive Learning Retrieval

DrumGAN VST: A Plugin for Drum Sound Analysis/Synthesis With Autoencoding Generative Adversarial Networks

no code implementations29 Jun 2022 Javier Nistal, Cyran Aouameur, Ithan Velarde, Stefan Lattner

In contemporary popular music production, drum sound design is commonly performed by cumbersome browsing and processing of pre-recorded samples in sound libraries.

Generative Adversarial Network Resynthesis

VQCPC-GAN: Variable-Length Adversarial Audio Synthesis Using Vector-Quantized Contrastive Predictive Coding

1 code implementation4 May 2021 Javier Nistal, Cyran Aouameur, Stefan Lattner, Gaël Richard

Influenced by the field of Computer Vision, Generative Adversarial Networks (GANs) are often adopted for the audio domain using fixed-size two-dimensional spectrogram representations as the "image data".

Modeling Musical Structure with Artificial Neural Networks

no code implementations6 Jan 2020 Stefan Lattner

Furthermore, I motivate the relevance of musical transformations in structure modeling and show how a connectionist model, the Gated Autoencoder (GAE), can be employed to learn transformations between musical fragments.

High-Level Control of Drum Track Generation Using Learned Patterns of Rhythmic Interaction

no code implementations2 Aug 2019 Stefan Lattner, Maarten Grachten

Here we propose a model for conditional kick drum track generation that takes existing musical material as input, in addition to a low-dimensional code that encodes the desired relation between the existing material and the new material to be generated.

Learning Complex Basis Functions for Invariant Representations of Audio

1 code implementation13 Jul 2019 Stefan Lattner, Monika Dörfler, Andreas Arzt

Mapping signals onto complex basis functions learned by the CAE results in a transformation-invariant "magnitude space" and a transformation-variant "phase space".

A Predictive Model for Music Based on Learned Interval Representations

no code implementations22 Jun 2018 Stefan Lattner, Maarten Grachten, Gerhard Widmer

We show that the RGAE improves the state of the art for general connectionist sequence models in learning to predict monophonic melodies, and that ensembles of relative and absolute music processing models improve the results appreciably.

Learning Transposition-Invariant Interval Features from Symbolic Music and Audio

no code implementations21 Jun 2018 Stefan Lattner, Maarten Grachten, Gerhard Widmer

Many music theoretical constructs (such as scale types, modes, cadences, and chord types) are defined in terms of pitch intervals---relative distances between pitches.

Learning Musical Relations using Gated Autoencoders

no code implementations17 Aug 2017 Stefan Lattner, Maarten Grachten, Gerhard Widmer

Music is usually highly structured and it is still an open question how to design models which can successfully learn to recognize and represent musical structure.

Open-Ended Question Answering

Improving Content-Invariance in Gated Autoencoders for 2D and 3D Object Rotation

no code implementations5 Jul 2017 Stefan Lattner, Maarten Grachten

Content-invariance in mapping codes learned by GAEs is a useful feature for various relation learning tasks.
