4. Physical Modeling Synthesizers: Physical modeling synthesizers use algorithms to simulate the behavior of physical objects, such as strings, brass, or woodwinds. They are capable of creating realistic sounds, but require a lot of processing power and can be complex to use.
5. Waveform Synthesizers: Waveform synthesizers use mathematical algorithms to generate sounds from scratch, rather than sampling existing sounds. They are capable of creating a wide range of sounds, from classic synth tones to more experimental textures.

Each type of hardware sampler has its own unique advantages and disadvantages, and choosing the right one depends on your specific needs and preferences. In the next section, we will explore some of the key features to consider when selecting a hardware sampler.

How does a hardware sampler work?

Sampling process

A hardware sampler is an electronic musical instrument that generates sound by playing back pre-recorded audio samples. The sampling process is the foundation of how hardware samplers work. The sampling process involves capturing and storing audio samples in the hardware sampler’s memory. The captured samples can then be manipulated using various parameters such as filtering, envelopes, and modulation to create new sounds.

To understand the sampling process, it is important to know that there are two types of sampling: single-point sampling and multi-point sampling. Single-point sampling involves capturing a single point in time of an audio signal, while multi-point sampling involves capturing multiple points in time of an audio signal. Multi-point sampling is used in hardware samplers to create more realistic and detailed sounds.

The sampling process begins with the capture of an audio signal using an analog-to-digital converter (ADC). The ADC converts the analog audio signal into a digital format that can be stored in the hardware sampler’s memory. The sampling rate, which is the number of samples per second, determines the accuracy of the captured audio signal. A higher sampling rate results in a more accurate representation of the original audio signal.

Once the audio signal has been captured, it is stored in the hardware sampler’s memory. The memory is organized into sample frames, which contain a set of samples that can be played back as a single sound. The number of samples in a frame is determined by the hardware sampler’s sample resolution.

The sample frames are then triggered by a note or MIDI event, which causes the hardware sampler to play back the stored samples. The samples can be played back in different ways, such as looped or randomized, to create new and unique sounds.

In addition to playing back the stored samples, hardware samplers also have various parameters that can be adjusted to manipulate the sound. These parameters include filtering, envelopes, and modulation. Filters are used to shape the frequency response of the sound, while envelopes are used to control the volume and duration of the sound. Modulation is used to create movement and expression in the sound.

Overall, the sampling process is the foundation of how hardware samplers work. By capturing and storing audio samples, hardware samplers are able to generate a wide range of sounds that can be manipulated using various parameters.

Hardware components

A hardware sampler relies on a series of specialized components to perform its function of sampling and reproducing sound. These components include:

Analog-to-digital converter (ADC)

The ADC is responsible for converting the analog audio signal into a digital format that the sampler can process. It does this by measuring the amplitude of the audio signal at specific intervals and converting these measurements into digital values.

Sample buffer

The sample buffer is where the digitized audio samples are stored temporarily before being processed further. It is typically a small amount of memory that allows the sampler to access and manipulate the samples quickly.

Digital signal processor (DSP)

The DSP is the brain of the hardware sampler. It is responsible for performing various operations on the digitized audio samples, such as filtering, resampling, and compression. The DSP uses complex algorithms to manipulate the samples and produce the desired sound.

Output stage

The output stage is where the processed audio samples are converted back into an analog signal that can be sent to an amplifier or speaker. It typically includes a digital-to-analog converter (DAC) that converts the digital audio signal back into an analog format.

Understanding the function of each of these components is crucial to understanding how hardware samplers work and how they can be used to produce high-quality sound.
