That will play the sounds on the board in random order. If you want the player to play an audio file randomly each time among all the files, you need to create a simple configuration file and put it together with the audio files in the root directory of the memory with a "2" in the config file.If there are multiple files in the internal memory, after each activation, the player will play an audio file at a time in sequence (from the first file to the last one in the loop) This is the default setting for all boards.An MP3 player is one kind of digital audio player or DAP that can play MP3 digital audio files. This module can also be used as a standalone module including a battery, pushbuttons, and speaker. Max Load Output: 200mA (For larger load attach a relay via the Busy Signal Output)Ĭonsumption Current at Playback: ≤500mA (12V DC) The MP3 Player is a tiny & cheap module that generates a simplified output that is directly given to the speaker. When a sound is playing, there is simultaneously a load output (up to 200mA max), which can directly drive a warning light, LED light, or LED strip. Supports multiple files that can be played back sequentially OR in random order Solder pads for audio signal out to external amplifier available on the back of the board.Īdjustable sound volume through the blue potentiometer.Ĭan be activated with a PIR sensor, microwave sensor, switch, or relay.

Typically, this results in simpler code but more buffering, which may affect latency. In push mode, the audio device provides a QIODevice instance that can be written or read to as needed. Conversely, for pull mode with QAudioSource, when audio data is available then the data will be written directly to the QIODevice. For an output device, the QAudioSink class will pull data from the QIODevice (using QIODevice::read()) when more audio data is required. In pull mode, the audio device is started by giving it a QIODevice. The low level audio classes can operate in two modes - push and pull. The available hardware determines what audio outputs and inputs are available. The QAudioSink class offers raw audio data output, while QAudioSource offers raw audio data input.
Generally these classes do not do any audio decoding, or other processing, but they can support different types of raw audio data.
The C++ API of Qt Multimedia offers classes for raw access to audio input and output facilities, allowing applications to receive raw data from devices like microphones, and to write raw data to speakers or other devices. Number of loops in which a sound effect is played.This class allows you to specify a WAV format file, which can then be played with low latency when necessary. In addition to raw access to sound devices, the QSoundEffect class (and SoundEffect QML type) offers a more abstract way to play sounds. QMediaCaptureSession also provides support for more complex use cases such as image capturing or video recording.
