Editing Your Sound in Audacity

Step 1: Import or Record

File > Import > Audio (for existing files)
Or click Record for new audio

Step 2: Trim to Length

Select the portion you want (1-5 seconds)
Edit > Trim (removes everything else)
Or use Delete to remove unwanted parts

Step 3: Set the Volume

Select all (Ctrl/Cmd + A)
Effect > Normalize
Set the peak to -1 dB
Click OK

Step 4: Fade In/Out (Optional)

Select first 0.1 seconds
Effect > Fade In
Select last 0.1 seconds
Effect > Fade Out

This prevents clicks and pops.

Step 5: Export Correctly

File > Export > Export as WAV
Set encoding: "Signed 16-bit PCM"
Name file LockChime.wav
Save to your Boombox folder

Setting the Correct Sample Rate

In Audacity

Check bottom-left corner shows 44100
If not: Tracks > Resample > 44100 Hz
Then: Edit > Preferences > Quality > Default Sample Rate: 44100

Converting Existing Files

If your sound is wrong format:

File > Import > Audio
Select all (Ctrl/Cmd + A)
Tracks > Resample > 44100 Hz
Export as WAV (16-bit PCM)

Sound Design Tips

Keep It Short

1-2 seconds is ideal for daily use
Under 5 seconds for special sounds
Longer sounds can be annoying over time

Consider the Frequency Range

The external speaker is small and built for outdoor sound. As a rule of thumb:

Clear, defined sounds are the safest choice
Very deep bass may not come through, so preview it first

Test Volume

Too quiet: Increase gain in Audacity
Too loud: Reduce the level and re-export
Listen on different devices before testing in car

Avoid Clipping

If sound is distorted:

Reduce overall volume
Use limiter effect
Lower the level and re-export

Folder Structure

Place your final file:

USB Drive/
└── Boombox/
    └── LockChime.wav

Testing Your Creation

Copy to USB drive
Insert USB in Tesla
Navigate to Toybox > Boombox > Lock Sound
Select USB and pick your sound
Lock car to test
Adjust if needed

Troubleshooting DIY Sounds

Sound Won't Play

Verify WAV format (not MP3)
Check sample rate is 44.1kHz
Confirm bit depth is 16-bit
Ensure file name is exact

Sound is Distorted

Peak volume too high
Lower the level and re-export
Remove excessive bass

Sound is Too Quiet

Set the peak to -1 dB
Add slight compression
Check source recording levels

Advanced Techniques

Layering Sounds

Combine multiple elements:

Import first sound
Import second on new track
Adjust timing and volume
Mix down: Tracks > Mix > Mix and Render

Adding Effects

Audacity includes:

Reverb (adds space)
Echo/Delay
Pitch shift
EQ/Filtering

FAQ

What audio format does Tesla require for custom lock sounds?

WAV format, 44.1kHz sample rate, 16-bit PCM (not 24-bit). The file must be named exactly LockChime.wav (case-sensitive) and placed in a folder named Boombox at the root of a FAT32-formatted USB drive. These specs work on all Tesla models. If you're editing in Audacity, export as "WAV (Microsoft)" with "Signed 16-bit PCM" encoding.

How long can a custom Tesla lock sound be?

1-3 seconds is the practical sweet spot. Tesla can play sounds up to around 5-6 seconds, but anything longer gets annoying quickly since it plays every time you lock. Keep the most distinctive part of your sound in the first 1 second: that's all you need for recognition.

Why won't my custom-made lock sound work on Tesla?

The most common DIY mistakes: (1) Wrong format: must be WAV, not MP3 or M4A. (2) Sample rate mismatch: must be exactly 44.1kHz. (3) 24-bit instead of 16-bit. (4) File or folder name wrong: must be LockChime.wav in Boombox. (5) USB format: must be FAT32 or exFAT. Check each of these in order.

Do I need special software to create a Tesla lock sound?

Audacity is free, well-documented, and handles everything you need: trimming, volume changes, sample rate conversion, and WAV export at the right spec. GarageBand (Mac) works too. If you just need format conversion without audio editing, our browser-based converter is the fastest option.

Can I record my own voice or sounds for a Tesla lock sound?

Yes. Recording your own audio is completely legal, it's your original content. Use Audacity's Record function, or record on your phone and transfer the file. Check the volume, trim to 1-3 seconds, and export as WAV at 44.1kHz 16-bit. Voice recordings work especially well because they're always unique.
