Morse Decoder AI vs CreamAudio Recorder

The Morse Decoder AI is an application for decoding Morse code signals using artificial intelligence. The application is designed for use by amateur radio enthusiasts for educational purposes. The Morse decoder listens to the audio stream through the microphone or line input and, upon detecting Morse code signals, decodes them into text. The neural network of the application is trained to decode signals with a speed ranging from 10 to 40 words per minute within a frequency range of 200 Hz to 900 Hz. The application supports two modes of operation: direct (default) and tone filtering mode. In direct mode, the neural network will attempt to decipher Morse code signals in the audio range of 250 Hz to 900 Hz. This mode is suitable for confident reception of Morse code at levels of 7db-9db on the S-meter. The tone filtering mode is ideal for decoding Morse code from noisy weak signals in the presence of radio interference. The audio input signal is first filtered using band-pass filters before being passed to the neural network for decoding. This mode allows for the decoding of faint signals, but it requires the accurate specification of the signal's tone frequency. Each radio amateur selects their own CW tone frequency in the transceiver settings, and it is important to tune precisely to the carrier frequency using the ZIN/SPOT button in YAESU transceivers, or the AUTOTUNE button in ICOM transceivers. There are 3 band-pass filter options available: 25Hz, 50Hz, 150Hz. If you can accurately determine the CW signal tone frequency, using the 25Hz filter, you can decode very faint Morse code signals. The application offers two neural network options: A and B, which can be easily switched in the interface. Network A is recommended for use with stable signal transmission with a constant duration of dots and dashes, while network B is recommended when using a straight key, where the duration of dots and dashes may vary. You have the ability to switch between these networks in real time and observe how each network hears and decodes Morse code. It is important to monitor the level of the incoming audio signal, for which the application provides a sound level indicator. Ensure that the signal is not too quiet or too loud. It is recommended to maintain the signal around -7db, which is sufficient for decoding. Keep in mind that higher audio frequencies are quieter than lower frequencies. Additionally, the application provides various color themes, allowing radio enthusiasts to customize the appearance of the application for comfortable use.

CreamAudio Recorder captures audio the way engineers and musicians need it: straight from the hardware, with nothing added and nothing taken away. MEASURE mode — unprocessed, by default Every recording starts in MEASURE mode, which turns off automatic gain control, noise suppression, and EQ so what hits the file is the raw, linear signal from the input — the built-in mic, or an attached USB/Thunderbolt/class-compliant audio interface. No smoothing, no "enhancement," no surprises — just a clean, faithful, repeatable recording. Built for acoustic measurement, instrument capture, room tone, and any use where accuracy matters more than a processed sound. DSP mode — Apple's stereo mic, when you want it (iPhone/iPad) Flip the switch to DSP mode on iPhone or iPad to hand the signal to Apple's mic-array processing and unlock true stereo capture from the built-in microphones, with the OS's natural-sound tuning (AGC/EQ/noise suppression) applied — good for interviews, ambience, and everyday recording where a fuller, processed sound is what you want. DSP mode only ever applies to the built-in mic; plug in an external interface and the signal is always the raw, unprocessed one. Recording Set your format before you hit record: WAV (24-bit PCM) or AAC (.m4a) at your choice of 96/128/192/256 kbps, recorded directly with no intermediate conversion Share a take straight from the app via the standard system share sheet — AirDrop, Messages, Mail, Save to Files, or any other app — in the format you recorded (WAV by default) Record-level gain boost up to +24 dB, with optional auto level Live stereo metering: switchable analog VU needle or segmented LED ladder Background recording continues when the app is backgrounded or the screen locks Universal: macOS, iPhone, and iPad CreamAudio Recorder is a paid app — a single purchase unlocks every feature described here. There are no subscriptions and no in-app purchases; all features are included.
