Abstract

Editing signals using large pre-trained models, in a zero-shot manner, has recently seen rapid advancements in the image domain. However, this wave has yet to reach the audio domain. In this paper, we explore two zero-shot editing techniques for audio signals, which use DDPM inversion on pre-trained diffusion models. The first, adopted from the image domain, allows text-based editing. The second, is a novel approach for discovering semantically meaningful editing directions without supervision. When applied to music signals, this method exposes a range of musically interesting modifications, from controlling the participation of specific instruments to improvisations on the melody.

1. Samples of Editing

We present samples of audio editing using our proposed methods. The samples are organized into two sections: text-based editing and unsupervised editing.

  1.1. Samples of Text-Based Editing

#	Source Prompt	Target Prompt	Original Audio	Edited Audio	Edit Tstart
1	A recording of a sneaky jazz song.	A recording of a tense classical music score.			110
2	A recording of a hard rock song.	A recording of a jazz song.			100
3	A recording of a happy upbeat classical music piece.	A recording of a happy upbeat arcade game soundtrack.			100
4	Trumpets playing alongside a piano, bass and drums in an upbeat old-timey cool jazz song.	A banjo playing alongside a piano, bass and drums in an upbeat old-timey cool country song.			90
5	——	A recording of a dark techno song.			90

1.2. Samples of Unsupervised Editing

For the unsupervised editing, we split the samples into two sections.
The first section (Strength changes) shows how the same direction applied with different strengths changes the audio sequentially.
The second section (PC direction changes) shows how removing or adding a direction removes or adds a concept.

  1.2.1. Various Samples (Strength changes)

#	Inversion Prompt	Original Audio	Edited Audio +PC	Edited Audio +2PC	PC Interpretation	Edit Parameters
1	A high quality recording of flutes and a trumpet playing.				Melody change	t'∈[200, -1] Specific t=80 used PCs 1+2+3
2	A recording of a calm country song.				Remove singer	t'∈[150, -1] Specific t=115 used PCs 1+2+3
