Overview

Audio Resample changes an audio file’s sample rate to a selected value from 8 kHz to 48 kHz, with optional channel selection and metadata preservation.

Convert stereo audio to mono for voice recordings or other single-channel uses.
Standardize sample rates across audio files before adding them to a project.

How it works

1Upload one supported audio file, such as MP3, AAC, M4A, OGG, Opus, FLAC, or WAV.
2Choose a target sample rate from 8, 12, 16, 22.05, 32, 44.1, or 48 kHz.
3Choose Auto to keep the original channel layout, or select mono or stereo.
4Enable or disable Keep Metadata, then create the resampled audio file.

Use cases

Examples

1. Resample a voice recording to 22.05 kHz

Podcast editor

Background

A podcast editor has a WAV voice recording captured at 44.1 kHz and needs a 22.05 kHz version.

Problem

The recording uses a different sample rate from the target audio workflow.

How to use

Upload the WAV file, select 22.05 kHz as the target sample rate, leave channels set to Auto, and keep metadata enabled.

Target sample rate: 22.05 kHz; Audio channels: Auto; Keep Metadata: enabled

Outcome

The tool produces a resampled audio file at 22.05 kHz while keeping the original channel layout and metadata setting.

2. Convert stereo audio to mono

Voice content creator

Background

A creator has a stereo M4A recording that needs to use one audio channel.

Problem

The source file has two channels, but the intended workflow requires mono audio.

How to use

Upload the M4A file, select the required target sample rate, choose Mono, and decide whether to keep metadata.
