Vocal Production Explained

When it comes to cleaning up vocals for clarity of pronunciation, the first thing to consider is the frequency range of the vocal. The most important frequencies in a vocal are typically between 1kHz and 5kHz, which is where the clarity and intelligibility of the vocal lies. This is where most of the consonant sounds like “s,” “t,” and “p” are located, and also where the natural resonance of the human voice occurs. However, there can also be some harsh or sibilant sounds in this frequency range that need to be reduced, which is where a de-esser comes in.

A de-esser is a tool that specifically targets the harsh, sibilant sounds that occur in the 4kHz to 10kHz range. It works by reducing the level of the audio signal in this frequency range whenever it exceeds a certain threshold, which can be adjusted to achieve the desired effect. A de-esser typically uses a high-pass filter to only target the relevant frequency range, and then applies a gain reduction to those frequencies.

When it comes to increasing the volume of a vocal track, compression is a common tool used in vocal mixing. Compression works by reducing the dynamic range of the signal, which means that it makes the loud parts quieter and the quiet parts louder. To set the attack and release times appropriately, it’s important to understand the rhythm and dynamics of the vocal performance. A faster attack time will allow the compressor to react more quickly to sudden, loud sounds, while a slower attack time will allow the initial transients of the vocal to come through before the compressor kicks in. Similarly, a shorter release time will allow the compressor to release the gain reduction more quickly, while a longer release time will allow the vocal to sustain naturally.

It’s also worth noting that the frequency range of the vocal can be affected by the microphone used for recording, as well as the recording environment. A good quality microphone that is designed for vocal recording can capture the natural resonance and tonality of the voice, while a poorly suited microphone can introduce unwanted coloration or distortion. Similarly, a well-treated recording environment can minimize the amount of unwanted noise and resonance that can interfere with the clarity of the vocal.

In summary, the frequency range of a vocal is typically between 1kHz and 5kHz, where the clarity and intelligibility of the vocal lies. A de-esser is a tool that can reduce harsh or sibilant sounds in the 4kHz to 10kHz range. Compression can be used to increase the overall volume of the vocal track, and the attack and release times should be set appropriately for the rhythm and dynamics of the performance. The microphone used for recording, as well as the recording environment, can also affect the frequency range of the vocal.

  1. Equalization (EQ): EQ is an essential tool for shaping the frequency response of a vocal track. When mixing vocals, it’s important to remove any unwanted frequencies that can muddy up the mix, and boost the frequencies that bring out the character of the vocal. For example, you can use a high-pass filter to remove any low-end rumble, and a low-pass filter to remove any harsh high frequencies. You can also use a bell curve EQ to boost the frequencies that add warmth, clarity, or presence to the vocal. For example, you can boost the frequencies around 2-3 kHz to bring out the presence, or boost the frequencies around 6-7 kHz to add air and sparkle to the vocal.
  2. Compression: Compression is a powerful tool that helps to control the dynamics of a vocal track. When mixing vocals, compression can help to smooth out the volume of the vocal, making it more consistent and easier to fit in the mix. For example, you can use a low ratio, slow attack, and fast release to gently compress the vocal and maintain its natural dynamic range. This will help to bring out the detail and nuance of the vocal performance, while also preventing it from getting lost in the mix during louder parts of the song.
  3. Reverb and Delay: Reverb and delay are effects that can help to add depth, space, and dimension to a vocal track. When mixing vocals, you can use reverb and delay to create a sense of ambience, or to give the vocal a more ethereal quality. For example, you can use a short plate reverb to add a subtle sense of space to the vocal, or a long hall reverb to create a more pronounced sense of depth. You can also use a short delay to create a sense of stereo width, or a longer delay to create a sense of echo and sustain.
  4. Vocal Bus Processing: Vocal bus processing is a technique used to apply processing to multiple vocal tracks at once. When mixing vocals, you can use a vocal bus to group together all the vocal tracks in the mix, and apply processing such as compression, EQ, and reverb to the group. This can help to create a cohesive sound for the vocals, and make them fit better in the mix. For example, you can use a parallel compression technique to add more sustain and body to the vocals, or use a bus EQ to shape the overall frequency response of the vocal group.
  5. Automation: Automation is the process of adjusting the volume, panning, and effects levels of a track over time. When mixing vocals, automation can be used to create a more dynamic and expressive performance. For example, you can automate the volume of the vocal track to bring out certain words or phrases, or to create a sense of dynamics and energy in the vocal performance. You can also automate the reverb and delay levels to create a sense of movement and space in the vocal.

Overall, when mixing vocals, it’s important to focus on the frequency range of the vocal, and use tools such as EQ, compression, and effects to shape its tone and dynamics. You also need to pay attention to how the vocal fits in the mix, and use techniques such as bus processing and automation to create a cohesive and expressive sound. The key is to experiment with different techniques and tools until you find the right balance for the song and the vocal performance.

Compression explained

Compression is a crucial tool in music production, as it helps to control the dynamic range of a signal, making it more consistent and easier to mix. Here are some best compression practices and explanations of attack, release, and threshold:

  1. Vocal Compression: When compressing a vocal track, it’s essential to use a light touch and maintain the natural dynamic range of the performance. Here are some settings to consider:
  • Threshold: Start with a threshold that reduces the dynamic range of the vocal by about 3-6 dB. This will ensure that the vocal is more consistent and easier to fit in the mix.
  • Ratio: Use a ratio of around 2:1 to 4:1. This will ensure that the vocal is still dynamic and expressive, but with a smoother and more controlled sound.
  • Attack: Use a medium attack time to allow the initial transient of the vocal to pass through untouched. This helps to preserve the natural character and clarity of the vocal.
  • Release: Use a release time that matches the tempo of the song. This will ensure that the compressor releases in time with the rhythm of the track, and avoids any pumping or breathing artifacts.
  1. Instrument Compression: When compressing instruments such as drums, bass, or guitar, it’s important to consider the role of the instrument in the mix and how it interacts with other elements. Here are some settings to consider:
  • Threshold: Start with a threshold that reduces the dynamic range of the instrument by about 3-6 dB. This will ensure that the instrument is more consistent and easier to fit in the mix.
  • Ratio: Use a ratio of around 4:1 to 8:1, depending on the instrument and its role in the mix. For example, you might use a higher ratio on a bass guitar to control its low-end energy, but a lower ratio on a cymbal to preserve its natural decay.
  • Attack: Use a fast attack time to capture the initial transient of the instrument, and bring it forward in the mix. This can help to make the instrument more present and energetic.
  • Release: Use a release time that matches the tempo of the song, or slightly longer. This will ensure that the compressor releases in time with the rhythm of the track, and avoids any pumping or breathing artifacts.
  1. Balancing Compression: When using compression to balance the levels of multiple tracks in a mix, it’s important to use a light touch and maintain the natural balance of the instruments. Here are some settings to consider:
  • Threshold: Start with a threshold that reduces the dynamic range of the tracks by about 1-3 dB. This will ensure that the tracks are more consistent and easier to blend together.
  • Ratio: Use a ratio of around 2:1 to 4:1, depending on the tracks and their roles in the mix. You might use a higher ratio on a lead vocal to bring it forward in the mix, but a lower ratio on a background vocal to keep it more subtle.
  • Attack: Use a medium attack time to allow the initial transients of the tracks to pass through untouched. This helps to preserve the natural character and clarity of the instruments.
  • Release: Use a release time that matches the tempo of the song. This will ensure that the compressor releases in time with the rhythm of the track, and avoids any pumping or breathing artifacts.

In summary, when using compression, it’s essential to consider the role of the instrument or vocal in the mix and adjust the settings accordingly. Threshold, ratio, attack, and release all have a significant impact on the sound of the compression, so it’s important to experiment with different settings until you find the right balance for the song and the mix.
