Use 48 kHz for video. It's the standard for film, TV and online video, YouTube's recommended upload settings specify it, and it divides evenly into common frame rates. 44.1 kHz is the CD and music-streaming standard, and is fine for audio-only work such as music and podcasts. The audible difference between them is negligible; the real problems come from mixing the two in one project.

Here's the difference in numbers, which rate to use for each kind of project, what happens when they're mixed, and how to fix it.
The short answer
48 kHz for anything with picture: YouTube's upload settings specify 48 kHz, and at 24, 25, 30 or 60 fps it gives a whole number of samples per frame (2,000, 1,920, 1,600, 800). 44.1 kHz for music and audio-only releases; Apple Podcasts accepts 44.1 or 48 kHz. Both capture everything people can hear (up to 22.05 kHz and 24 kHz). Never mix them in one timeline without conversion: a 44.1 kHz file played as 48 kHz runs 8.8% fast and drifts out of sync.
Key takeaways
- 48 kHz = video standard; 44.1 kHz = CD and music standard.
- Both cover the full range of human hearing (about 20 kHz); 48 kHz adds a little headroom.
- 48,000 ÷ 30 = 1,600 samples per frame; 44,100 ÷ 24 = 1,837.5, not a whole number.
- Mismatched rates cause pitch shifts, clicks or slow drift out of sync.
- Record and edit at one rate; convert music to 48 kHz before it goes into a video edit.
What is the difference between 44.1 kHz and 48 kHz?
The difference between 44.1 kHz and 48 kHz is how many times per second the audio is measured: 44,100 or 48,000. A higher sample rate can represent higher frequencies; the limit (the Nyquist frequency) is half the sample rate.
| 44.1 kHz | 48 kHz | |
|---|---|---|
| Samples per second | 44,100 | 48,000 |
| Highest frequency it can hold | 22.05 kHz | 24 kHz |
| Where it's standard | CDs, music streaming, much music production | Video, film, TV, DVD and Blu-ray, video platforms |
| Samples per video frame at 30 fps | 1,470 | 1,600 |
| WAV size, 16-bit stereo, per minute | 10.6 MB | 11.5 MB |
Human hearing tops out around 20 kHz, and lower for most adults, so both rates capture everything audible. In a blind listening test, nobody reliably tells them apart. Choose by where the audio is going, not by sound quality.
Which sample rate should you use for video?
Use 48 kHz for video. YouTube's recommended upload encoding page specifies a 48 kHz sample rate for audio, and video editors default to it. 48 kHz also lines up neatly with frame rates, so audio edits fall on exact sample boundaries at every frame:
| Frame rate | Samples per frame at 48 kHz | Samples per frame at 44.1 kHz |
|---|---|---|
| 24 fps | 2,000 | 1,837.5 |
| 25 fps | 1,920 | 1,764 |
| 30 fps | 1,600 | 1,470 |
| 60 fps | 800 | 735 |
| 23.976 fps | 2,002 | 1,839.34 |
| 29.97 fps | 1,601.6 | 1,471.47 |
Editors handle fractional cases fine, but the safest workflow is to record at 48 kHz on every device (camera, recorder, microphone, computer), set the project to 48 kHz and export at 48 kHz.
Which sample rate should you use for podcasts and music?
For podcasts, either works; for music, 44.1 kHz is the traditional delivery rate. Apple Podcasts' audio requirements, read in October 2026, ask for at least 44.1 kHz in WAV or FLAC uploads, list 44.1, 48 kHz and higher as recommended rates, and recommend 44.1 or 48 kHz for MP3 and AAC files in RSS feeds.
| Project | Use |
|---|---|
| YouTube, social video, film, TV | 48 kHz |
| Video podcast | 48 kHz (matches the video) |
| Audio-only podcast | 44.1 or 48 kHz; stay consistent |
| Music release, CD | 44.1 kHz (or record higher and convert at the end) |
| Voiceover for a video | 48 kHz |
| Game or app audio | Whatever the engine expects, often 48 kHz |
Some apps choose for you: Apple's QuickTime Player records audio at 44,100 Hz (AAC at High quality, or 24-bit uncompressed at Maximum), so convert those recordings to 48 kHz before editing them into a video, or let your editor convert them on import.
What happens if you mix 44.1 kHz and 48 kHz?
If you mix 44.1 kHz and 48 kHz without conversion, the audio plays at the wrong speed or slowly drifts out of sync. When a file is read at the wrong rate, everything shifts by the ratio between them, 48,000 ÷ 44,100 = 1.088:
| Mistake | Effect | On a 10-minute file |
|---|---|---|
| 44.1 kHz audio played as 48 kHz | 8.8% faster, about 1.5 semitones higher | Ends about 49 seconds early |
| 48 kHz audio played as 44.1 kHz | 8.1% slower, about 1.5 semitones lower | Runs about 53 seconds long |
| Device set to one rate, app to another | Clicks, crackles or gradual drift | Varies |
Larry Jordan describes slow sync drift as a classic symptom of shooting audio at one sample rate and capturing it at another. Modern editors resample automatically when you import, so the big errors above mostly appear when a recorder, an audio interface or an operating system setting disagrees with the app. On Windows, check the device's default format in Sound settings; on a Mac, check Audio MIDI Setup. If audio is already out of sync, how to fix audio out of sync with video walks through the fixes.
Should you record at 96 kHz?
Usually not for video. 96 kHz doubles the file size and captures frequencies far above hearing. It helps in two cases: heavy pitch or time-stretching (sound design, slowing down effects), and some music production workflows. For speech and video, 48 kHz at 24-bit gives plenty of headroom. Bit depth matters more than sample rate for recording levels: 24-bit lets you record with more safety margin below clipping.
| Format | WAV size per minute (stereo) |
|---|---|
| 44.1 kHz, 16-bit | 10.6 MB |
| 48 kHz, 16-bit | 11.5 MB |
| 48 kHz, 24-bit | 17.3 MB |
| 96 kHz, 24-bit | 34.6 MB |
How do you check or change a file's sample rate?
You check a file's sample rate in its properties (Windows: right-click > Properties > Details; Mac: Get Info, or the Inspector in QuickTime) or in any editor's clip info. To change it, export or convert at the new rate:
- Audacity: set Project Rate to 48000, then export.
- FFmpeg:
ffmpeg -i in.wav -ar 48000 out.wav(for a video, add-c:v copyto leave the picture untouched). - In your browser: the free audio extractor saves a video's sound as a 16-bit WAV at your device's audio sample rate, usually 44.1 or 48 kHz. That's why a WAV can come out at 48 kHz from a 44.1 kHz video: the device's rate wins.
The free voice recorder also records at your microphone's own sample rate, so set the microphone to 48 kHz in your system's sound settings if the recording is going into a video. For file sizes at each rate, see video file size per minute.
Frequently asked questions
Is 48 kHz better than 44.1 kHz?
Not audibly. 48 kHz is the video standard and 44.1 kHz the music standard; both capture the full range of human hearing.
What sample rate should I use for YouTube?
48 kHz. YouTube's recommended upload settings specify a 48 kHz sample rate.
Can I use 44.1 kHz audio in a video?
Yes; editors convert it. Just don't mix rates in a recording chain without conversion, or you risk drift.
Why does my audio sound sped up or chipmunk-like?
It's probably being played at the wrong sample rate, such as a 44.1 kHz file read as 48 kHz. Match the device and project rates.
What sample rate does Spotify or Apple Music use?
Music is commonly mastered and distributed at 44.1 kHz; check each distributor's specs for higher-resolution options.
Does a higher sample rate make voice sound better?
No. For speech, the microphone, the room and the levels matter far more than going above 48 kHz.
