The WAV Trigger is a unique high-fidelity polyphonic audio player with surprising capabilities. Supporting up to 2048 uncompressed 16-bit, 44.1kHz wav files – the same quality as an audio CD – the WAV Trigger can play and mix up to 14 stereo tracks simultaneously and independently, with very low latency. Tracks can be controlled via 16 programmable trigger inputs, or by using a native serial control protocol or even MIDI.
Trigger inputs can be connected directly to switches and buttons, or to digital outputs from sensors or another microcontroller. Alternate functions can be specified using a free cross-platform GUI application, and allow triggers to play sequential or random tracks, pause and resume groups of tracks and even control volume. An Arduino library allows for complex serial control like real-time mixing, starting multiple tracks in sample-sync and smooth cross-fading between tracks.
On-board sample rate conversion allows for smoothly changing playback speed/pitch from 0.5x to 2x. in real-time.
MIDI allows you to use the WAV Trigger as a polyphonic sampling synthesizer to play your own sounds from any MIDI keyboard controller. MIDI Channels and Note numbers are mapped to track numbers, and MIDI Controllers adjust volume as well as attack and release times. MIDI Program Change is supported to switch between up to 16 banks of 128 sounds. The WAV Trigger audio engine even implements, pitch bending, voice stealing (oldest playing voices are used for new MIDI Notes when all 14 voices are being used), note attack (fade-in), note release (fade-out) and latency averages 8 ms.
The WAV Trigger supports both SDSC (up to 2GB) and SDHC (up to 32GB) type microSD cards.

該WAV觸發器是一種獨特的高保真和弦音頻播放器以驚人的能力。支持多達2048個未壓縮的16位,44.1kHz的WAV文件 - 相同質量的音頻CD - 的WAV觸發器可以播放和混合起來同時獨立14立體聲音軌,以非常低的延遲。曲目可以通過16個可編程觸發輸入,或通過使用本地串口控制協議,甚至MIDI控制。
觸發輸入可直接連接到開關和按鈕,或來自傳感器或其它微控制器的數字輸出。備選功能可以使用免費的跨平台GUI應用程序指定,並允許觸發播放順序或隨機的曲目,暫停和恢復軌道的團體,甚至控制音量。一個Arduino庫允許像實時混合複雜的串行控制,從樣品同步和軌道之間的平滑交叉漸變多首曲目。
板載採樣率轉換允許從0.5倍平穩改變播放速度/間距2倍。實時。
MIDI允許您使用WAV觸發作為採樣複音合成器從任何MIDI鍵盤控制器播放自己的聲音。 MIDI通道和注號碼映射到跟踪數字和MIDI控制器調節音量以及攻擊和釋放時間。 MIDI程序變更支持多達16家銀行的128聲音之間切換。該WAV觸發音頻引擎甚至農具,音高彎曲,語音偷(最早播放的聲音被用於新的MIDI音符時,正在使用的所有14個聲音),注意攻擊(淡入),說明發布(淡出)和時延的平均值8毫秒。
該WAV觸發器支持SDSC(最大2GB)和SDHC(最大32GB)類型的microSD卡。
