Microchips of the WT588D series combine two key positive differences from other possible options for storing and playing sound - this is the high quality of the sound itself and the flexibility of software settings.
The WT588D series has a wide sample rate range of 6 kHz to 20 kHz (mp3 sound quality level).
High quality sound is provided by a special optimized compression algorithm with minimal distortion.
The data inside the WT588D series is stored in 16-bit format.
Sampling rate selection is done entirely in software, so there is no need to change the frequency setting resistor.
There are also six software-selectable modes of operation of the microcircuit and 15 modes for each control line, which makes it possible to customize the WT588D for any necessary task.
Simple and user-friendly software allows you to quickly select all options and arrange audio files in the desired sequence.
Loading the finished project into the microcircuit is carried out using a USB programmer.
