Techniques and Tips
Here are some practical techniques for using synthesizers in sound design for electronic music.
Modulation with LFOs and Envelopes: Modulators like LFOs (low-frequency oscillators) and Envelopes (ADSR) can create motion in sound. LFOs can be routed to any parameter you wish to modulate, such as filter cutoff, oscillator pitch, and amplitude.
This technique is most effective with parameter values that are already fluctuating. For instance, if you route an LFO to pitch, you can achieve a slow upward modulation of the pitch value, combined with a rapid modulation around that point, resulting in a warbling effect. Envelopes are particularly useful for introducing dynamic movement within a sound, such as a gradual attack followed by a quick decay for percussion sounds.
Envelope parameters can also be modulated by an LFO, allowing for a scenario where the attack of a sound varies slowly while its volume changes rapidly. Additionally, modulating the volume of a sound can create effects like flanging or phasing, with the LFO modulating the filter frequency at a fast rate; this technique serves as the foundation for a wide variety of effects. Modulating parameters such as pitch, pulsation, and filtering can introduce depth and motion, making sounds feel more organic.
Filter Types: Low Pass (LP), High Pass (HP), Band Pass (BP), and Notch: Filters are another common method used in sound design. These include LP, HP, BP, and notch filters. Filters can reduce unwanted frequencies and also shape a sound’s character. For example, LP filters are often employed to diminish high frequencies in bass sounds. When designing sounds, it is essential to consider the type of sound being created and the frequency range of the notes involved. Utilizing filters in sound design can help achieve the desired character and tone while effectively reducing unnecessary frequencies.
Effect Types: Reverb, Delay, Chorus, Distortion/Overdrive, and Equalizers/Compressors: Effects are also vital techniques in sound design. Effects such as reverb and delay can add depth and space to a sound. For instance, reverb frequencies can be modulated with an LFO to create a sensation of movement through space. Similarly, modulating delay feedback levels can create a delay that feels dynamic and shifting. Adding distortion or overdrive can enhance the character of EDM sounds, while equalizers can help eliminate extraneous frequencies. Compression can be utilized to produce a more dynamic sound.
These foundational sound design techniques provide an excellent starting point for experimentation. Each technique is governed by its own mathematical functions that can be adjusted to create new sounds. Experimenting with these functions is key to discovering parameters that can be varied to generate innovative sounds. Sounds that convey a story are often not static; rather, they exhibit dynamic evolution and movement.
