## What is DitDah Decoder?

DitDah Decoder is a professional-grade Morse code communication tool designed for amateur radio operators and CW enthusiasts. Using advanced technology, it decodes Morse code from audio in real-time and lets you send messages back.

DECODE MORSE CODE
• Real-time audio decoding from your microphone or use an external adapter to receive directly from your radio
• Q-code and abbreviation translation
• Saves audio recordings of your decoding sessions
• Autocorrect button for reprocessing of saved audio files using neural networks

SEND MORSE CODE
• Type messages and transmit as Morse code audio
• Adjustable frequency and speed (WPM)
• Repeat send mode for calling CQ
• Use an external adapter to transmit directly via your radio
• Two people using the app can easily send messages back and forth on the air

COMPLETE LOGBOOK
• Automatic call sign detection with country lookup
• Organized by date and call sign
• Tap on any call sign to see stats
• QSO tracking and confirmation
• Adif export

Whether you're a licensed amateur radio operator working CW on the bands or learning Morse code, DitDah Decoder provides the tools you need for two-way Morse communication.


## Version history (last 4 releases)

### 2.0.0 — 2026-08-04

Version 2.0 is the biggest decoder upgrade since DitDah Decoder launched.

• All-new decoding engine: timing, spacing, and character patterns are now decided together probabilistically instead of by fixed thresholds — dramatically better accuracy on real-world signals, weak stations, and fading (QSB)
• Auto Gain and Adaptive Threshold have been overhauled to work together automatically — the default settings now work best, with no manual tuning needed
• Redesigned signal meter that shows the true signal level, noise floor, and the decoder's actual detection point
• New Text Revisions mode: decoded text appears sooner, and the decoder may briefly refine the last few characters as more audio arrives — like predictive text (can be turned off)
• Many bug fixes and stability improvements

### 1.4.5 — 2026-07-04

• Improved recording quality with a new 16 kHz audio pipeline — saved recordings are smaller and decode more accurately
• New Input Level and Signal Clipping indicators while listening
• More accurate neural autocorrect, including fixes for numbers
• Long recordings are now autocorrected per message segment
• Bug fixes and stability improvements

### 1.4.4 — 2026-01-19

New and improved logbook

### 1.4.3 — 2026-01-08

No release notes.
