RetroSampler is a lo-fi sample player inspired by hardware samplers of the 90s. It features adjustable sample and bit rate, clock jitter control, low pass filter with drive control and a integrated ADSR envelope. Lowering the sample rate will introduce the sought-after "ringing" effect found in older samplers which is not just a simple decimation effect: the resampling algorithm accurately follows the transposed pitch without interpolation.
There's also a full version with more features called RetroSampler Pro.
Runs on 64bit Windows and Mac (Intel+Apple Silicon) systems.
