Overview

The Audio Resample tool allows you to change the sample rate of audio files, such as converting from 44.1kHz to 22.05kHz, to adjust for compatibility, reduce file size, or meet specific technical requirements.

When to use

When you need to make audio files compatible with devices or software that require specific sample rates.
To reduce the file size of audio recordings by lowering the sample rate for storage or streaming efficiency.
When standardizing audio for professional applications like CD production or video editing that use common sample rates.

How it works

1Upload your audio file in a supported format such as MP3, WAV, or AAC.
2Choose the target sample rate from the available options, ranging from 8kHz to 48kHz.
3Optionally select the audio channels (mono, stereo, or auto) and decide whether to retain metadata.
4Process the file and download the resampled audio in the same or a compatible format.

Use cases

Optimizing audio files for mobile applications where lower sample rates save bandwidth and storage.
Converting studio recordings to standard sample rates like 44.1kHz for CD production.
Preparing audio assets for video projects that require 48kHz sample rate for synchronization.

Examples

1. Reduce File Size for Podcast Distribution

Content Creator

Background

A content creator has podcast episodes in high-quality 48kHz WAV format but needs to distribute them online with smaller file sizes.

Problem

Large audio files lead to slow downloads and high hosting costs.

How to use

Upload the WAV file, select 22.05kHz as the sample rate, and choose mono channels to minimize size.

sampleRate: 22050, channels: 1

Outcome

The resampled audio is significantly smaller, making it easier to distribute and stream without compromising spoken audio clarity.

2. Adapt Audio for Legacy Telephony System

System Administrator

Background

An administrator needs to update audio prompts for an old telephony system that only supports 8kHz sample rate.

Problem

Current audio files are in 44.1kHz, causing compatibility issues with the system.

How to use

Upload the audio file, set the sample rate to 8kHz, and keep channels as auto to match the original.

FAQ

What audio file formats can I upload?

You can upload MP3, AAC, M4A, OGG, Opus, FLAC, and WAV files.

Will the audio quality change after resampling?

Resampling may affect quality, particularly when reducing the sample rate, but standard algorithms are used to preserve audio integrity.

Can I choose to keep the original audio channels?

Yes, you can set channels to 'Auto' to keep the original, or select Mono or Stereo as needed.

Is there a limit on file size?

Yes, the maximum file size for upload is 125MB.

Does the tool preserve metadata like artist and title?

By default, metadata is kept, but you can uncheck the 'Keep Metadata' option to remove it.
