An audio trimmer (also called an audio cutter or audio clipper) is a tool that allows you to cut and extract specific portions of audio files. Whether you need to remove unwanted sections, create ringtones, extract highlights from podcasts, or trim silence from recordings, an audio trimmer makes it simple and fast.

Our free online audio trimmer works entirely in your web browser without requiring any software installation. Simply upload your audio file, select the start and end times, and download the trimmed result as a WAV file.

Understanding Time Formats

Seconds Format

Our tool uses seconds as the time unit. Here's how to convert:

• 1 minute = 60 seconds
• 1 minute 30 seconds = 90 seconds
• 2 minutes 15 seconds = 135 seconds
• 5 minutes = 300 seconds

Decimal Precision

You can use decimals for sub-second precision:

• 5.5 seconds = 5 seconds and 500 milliseconds
• 10.25 seconds = 10 seconds and 250 milliseconds
• 30.75 seconds = 30 seconds and 750 milliseconds

Best Practices for Audio Trimming

Find Exact Timestamps

• Use the built-in audio player to navigate
• Play and pause to find exact cut points
• Note the timestamp shown in the player
• Add a small buffer (0.1-0.2 seconds) to avoid cutting words

Preview Before Downloading

• Always preview your selection first
• Listen for cut-off words or abrupt endings
• Adjust times if needed
• Ensure smooth transitions

Optimize for Purpose

• Ringtones: 15-30 seconds, start with a strong beat or hook
• Social media: 15-60 seconds for maximum engagement
• Highlights: Include context, not just the key moment
• Samples: Extract clean sections without overlapping sounds

Troubleshooting Common Issues

File Won't Upload

If your audio file won't upload:

• Ensure it's an audio file (not video or document)
• Check file size (under 100MB recommended)
• Try a different audio format
• Refresh the page and try again

Preview Not Playing

If preview doesn't work:

• Check browser audio permissions
• Ensure volume is turned up
• Verify start time is less than end time
• Try a different browser

Trimmed Audio Sounds Cut Off

If words are cut off:

• Add 0.1-0.2 seconds buffer to start time
• Extend end time slightly
• Listen to the original at those timestamps
• Adjust and preview again

End Time Won't Accept Value

If end time input doesn't work:

• Ensure end time is greater than start time
• Check that end time doesn't exceed audio duration
• Verify you're using numbers only (no colons)
• Use decimal point, not comma (5.5, not 5,5)

Creating Perfect Ringtones

Ideal Length

Most phones support ringtones up to 30-40 seconds, but 15-25 seconds is optimal:

• Long enough to recognize the song
• Short enough to not annoy if unanswered
• Includes the best part (chorus, hook, or beat drop)

Best Starting Points

• Chorus: Most recognizable part of the song
• Intro: If it has a strong hook or beat
• Beat drop: For electronic or dance music
• Signature riff: For rock or guitar-heavy songs

Avoid These Sections

• Slow intros or outros
• Quiet verses
• Instrumental breaks (unless very distinctive)
• Fade-ins or fade-outs

Podcast Editing Tips

Removing Mistakes

To remove a mistake or unwanted section:

• Find the timestamp just before the mistake
• Find the timestamp just after the mistake
• Create two trimmed files (before and after)
• Use an audio joiner to merge them back together

Extracting Highlights

For creating promotional clips:

• Choose 30-60 second segments
• Include complete thoughts or questions
• Start and end at natural pauses
• Ensure context is clear

Technical Details

How Trimming Works

Our tool uses the Web Audio API to:

• Decode your audio file into an AudioBuffer
• Extract the specified time range
• Create a new buffer with only that section
• Encode it as a WAV file for download

Output Format

Trimmed audio is saved as WAV because:

• Uncompressed quality preserves all audio data
• Universal compatibility
• No generation loss
• Easy to convert to other formats later

Security and Privacy

Your audio files are completely secure:

• All processing happens in your browser
• Files are never uploaded to our servers
• No data is stored or logged
• Your audio remains completely private
• Once you close the browser, all data is cleared

Frequently Asked Questions

What audio formats can I trim?

You can upload MP3, WAV, OGG, M4A, FLAC, and most common audio formats. The output is always WAV for maximum quality.

How do I convert minutes to seconds?

Multiply minutes by 60. For example: 2 minutes 30 seconds = (2 × 60) + 30 = 150 seconds.

Can I trim multiple sections from one file?

Currently, you can trim one section at a time. To remove multiple sections, trim each separately and use an audio joiner to combine them.

Why is the output file WAV instead of MP3?

WAV is uncompressed and maintains perfect quality. You can convert the WAV to MP3 later if needed using a converter.

Is there a limit on file size or duration?

For best performance, we recommend files under 100MB. Very long files may take longer to process.

Can I trim audio from videos?

No, this tool is for audio files only. You'll need to extract the audio from the video first using a video converter.

Is my audio data safe?

Absolutely. All processing happens in your browser. Your files never leave your device.

Can I use trimmed audio commercially?

Our tool is free to use, but ensure you have rights to the original audio content before using it commercially.
