The spectrum and waterfall displays have been enhanced with new functionality. SWLtools: The Companion for Shortwave Listening Enthusiasts SWLtools is an app designed specifically for Shortwave Listening (SWL) enthusiasts who want to enhance their listening experience. Whether you are a hobbyist or a dedicated DXer, SWLtools provides useful tools to support your activity. Key Features Audio Recording and Storage Easily record and store audio directly from your receiver. Capture signals from around the world and listen to them again whenever you want. Spectrum and Waterfall Display If your receiver provides an IQ output, SWLtools can display the real-time spectrum and spectrogram (waterfall). Visually explore the bands and gain deeper insight into the signals you are receiving. Optimized for the Belka Receiver SWLtools was designed to work seamlessly with the Belka receiver. It’s the perfect companion for outdoor listening sessions, allowing you to record your DX or explore frequencies using the spectrum view. The app is optimized for low power consumption when displaying the spectrum and waterfall, making it ideal for portable use. Requirements To use SWLtools, you need an inexpensive USB audio adapter (ADC/DAC) connected to your iOS device. These affordable dongles typically provide a microphone input and a headphone output, allowing you to pass through the audio signal for recording or the IQ signal for spectrum display. With some adapters designed for line-level input and output, it is also possible to listen to your radio directly through the iPhone speakers. Not Just for SWL Although SWLtools is tailored for shortwave listeners, it can be used in any situation where you need to record an audio signal coming from a line output. Note: Please make sure your receiver is compatible with the app’s features and that you have the required accessories for optimal performance.

Ratings & Reviews

This app has not received enough ratings or reviews to display an overview.

Stereo and mono inputs on the ADC converter are now handled differently. Improved control over signal levels and AGC. The tuned station is now centered in the spectrum and waterfall displays, making precise tuning easier. Added a zoom function to the spectrum and waterfall displays. Added a cursor to measure bandwidth, RTTY shift, etc. on the waterfall display. Bug fixes and stability improvements.
