Overview

The Video to AAC Converter extracts audio from video files and converts it to AAC format. You can customize bitrate, sample rate, and audio channels, with an option to preserve metadata like title and artist tags.

When to use

  • When you need to extract audio from a video for playback on audio-only devices like MP3 players or smartphones.
  • To reduce file size by converting video audio to the efficient AAC format for storage or sharing.
  • When standardizing audio across multiple video files to ensure consistent quality and compatibility.

How it works

  1. 1Upload your video file in supported formats such as MP4, MOV, MKV, AVI, WebM, FLV, MPEG, or WMV.
  2. 2Select output settings: choose a bitrate from 96 to 320 kbps, set sample rate (auto, 44.1 kHz, or 48 kHz), and audio channels (auto, mono, or stereo).
  3. 3Optionally enable the 'Keep Metadata' checkbox to preserve available tags like title and artist.
  4. 4Download the converted AAC audio file directly to your device.

Use cases

  • Extracting audio from video podcasts or interviews for distribution on audio-only platforms like Spotify or Apple Podcasts.
  • Converting lecture or meeting recordings to audio files for convenient listening during commutes or workouts.
  • Preparing background music or sound effects from video clips for use in presentations, videos, or other creative projects.

Examples

1. Extract Podcast Audio from Video Interview

Podcaster

Background

A podcaster records interviews using video equipment and needs to publish the audio version for podcast listeners.

Problem

Manually extracting audio from video is time-consuming and risks quality loss or metadata issues.

How to use

Upload the video interview file, set bitrate to 192 kbps for balanced quality, and ensure 'Keep Metadata' is enabled to retain episode details.

Bitrate: 192 kbps, Sample Rate: Auto, Channels: Stereo, Keep Metadata: Yes

Outcome

A high-quality AAC audio file ready for podcast distribution, with metadata like title and artist preserved.

2. Convert Lecture Videos to Audio for Study

Student

Background

A student has recorded lecture videos and wants to listen to them while commuting without using video playback.

Problem

Video files are large and inconvenient for audio-only consumption on mobile devices.

How to use

Upload the lecture video, choose a lower bitrate like 128 kbps to save storage space, and set channels to mono if the audio is primarily speech.

FAQ

What video formats are supported?

The tool supports MP4, QuickTime, Matroska, AVI, WebM, FLV, MPEG, and WMV formats.

How do I choose the right bitrate?

Higher bitrates like 256 or 320 kbps offer better audio quality but larger files; 128 or 192 kbps are suitable for most general uses.

What is AAC format?

AAC is a high-quality audio compression format commonly used for streaming, portable devices, and online platforms.

Can I keep the original metadata?
