DECODER / AUDIO

Audio Morse Decoder

Upload MP3 or WAV or request microphone access. Automatic decoding of arbitrary recordings is beta and may not return a result.

One Morse decoder system, optimized for the source you already have.

HOW TO USE THIS DECODER

How to use the Audio Morse Decoder

Four practical steps illustrated with the same controls and results you see in the decoder above.

Uploading audio into the Audio Morse Decoder interface — **Figure 1. Upload or record**Listen through your microphone, or choose an MP3 or WAV recording from your device.

Step 1

Upload or record

Audio Morse Decoder waveform showing Morse signal detection — **Figure 2. Detect signal**The waveform shows the listening state. Verified samples demonstrate tone-and-pause analysis; arbitrary recordings are not yet decoded reliably.

Step 2

Detect signal

Morse audio timing analysis showing dots, dashes, and pauses in a CW signal — **Figure 3. Analyze timing**Check how short tones, long tones, and pauses become dots, dashes, characters, and words.

Step 3

Analyze timing

Process of converting Morse audio signals into readable text — **Figure 4. Decode text**When a result is present, review the Morse and text together. If no result appears, the file was received but not decoded.

Step 4

Decode text

Visual explanation

How audio becomes readable Morse

The workspace keeps each transformation understandable while advanced controls remain optional.

Audio Waveform
Upload MP3 or WAV, or record with your microphone.
Signal Detection
The waveform separates tones from pauses and steady noise.
Timing Analysis
Short and long tones become dots, dashes, letters, and words.
Text
Review the Morse pattern and readable message together.

Why use the Audio Morse Decoder?

Use the audio workspace to upload MP3 or WAV recordings, request microphone access, and inspect the intended signal-analysis flow. Automatic interpretation of arbitrary recordings is still beta.

Supported formats

Supported audio:

MP3
WAV
Recordings
Radio audio

Best results

Clear signal — use distinct tones and pauses.
Low background noise — reduce voices, music, and static.
Stable volume — avoid clipping and distortion.
Compare waveform timing before accepting the decoded text.

AUDIO DECODER QUESTIONS

Audio Morse Decoder, explained

Can I decode Morse from audio?

You can upload a Morse recording or request microphone access. Verified samples demonstrate decoding, but arbitrary uploads and live recordings are not yet interpreted reliably.

What audio formats work?

The audio decoder supports MP3 and WAV uploads, plus live microphone recording on compatible browsers.

How can I improve an audio result?

Use a clear, steady tone with limited background noise and consistent spacing. These conditions help analysis but do not guarantee a decoded result in the current beta.
