Tesla's Sound Requirements

Your sound must meet these specs:

●Format: WAV (uncompressed)

●Sample Rate: 44.1kHz (44100 Hz)

●Bit Depth: 16-bit

●Duration: 1-5 seconds recommended

●File Name: LockChime.wav

●Peak Volume: -3dB to -6dB

Option 1: Record Your Own Sound

Using Your Phone

Use a voice memo or recording app
Record in a quiet environment
Keep it 1-5 seconds
Export or transfer to computer
Convert and edit (see below)

Using a Microphone

Connect mic to computer
Open Audacity
Click Record button
Capture your sound
Stop and edit

●Your voice saying something

●Musical instrument notes

●Household sounds

●Nature recordings

●Pet sounds (short bark, meow, etc.)

Option 2: Create Digital Sounds

Using Audacity

Open Audacity
Generate > Tone (for simple beeps)
Generate > Noise (for texture)
Layer multiple sounds
Add effects

Free Sound Libraries

Important: Verify licensing before using any downloaded sounds.

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: Normalize Volume

Select all (Ctrl/Cmd + A)
Effect > Normalize
Set to -3dB or -6dB
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

Tesla's exterior speakers work best with:

●Mid-range frequencies (1-5kHz)

●Clear, defined sounds

●Minimal deep bass (won't reproduce well)

Test Volume

●Too quiet: Increase gain in Audacity

●Too loud: Reduce and normalize

●Listen on different devices before testing in car

Avoid Clipping

If sound is distorted:

●Reduce overall volume

●Use limiter effect

●Re-normalize to -6dB

Folder Structure

Place your final file:

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

Testing Your Creation

Copy to USB drive
Insert USB in Tesla
Navigate to Sentry Mode > Custom Sound
Select 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

●Re-normalize to -6dB

●Remove excessive bass

Sound is Too Quiet

●Normalize to -3dB

●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 or unlock. 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 normalization, 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. Run it through normalization to set volume correctly, trim to 1-3 seconds, and export as WAV at 44.1kHz 16-bit. Voice recordings work especially well because they're always unique.
