Vocal Features

ASTERIAN is an English-native bass vocalist that provides professional quality vocals for your projects whenever they are needed. Featuring a smooth bass range that smoothly transitions into a unique falsetto register, ASTERIAN makes a usually hard-to-find voice style easy to access any time. Users of ASTERIAN have control over all aspects of the melody and pitch and many other aspects of the voice like tension and breathiness, making ASTERIAN a vocalist with infinite possible applications.

Range: Bass (E2-D4) + Falsetto (G4-C5)
Tempo: 80-160 BPM
Voice Provider: Eric Hollaway
Recorded Language: English

Range: -- (Falsetto: -) | Suggested Combinations: Open, Strained

ASTERIAN's "Clear" vocal mode adds a degree of brightness and thins out some of the additional resonance in his voice. This can be used in small amounts to help cut through a mix, or in large amounts to change the vocal tone more drastically.

Range: -- (Falsetto: -) | Suggested Combinations: Clear, Gentle

The vocal mode "Warm", like "Clear", also adds a degree of brightness, but it also adds a more subtle characteristic in reducing the roundness of ASTERIAN's pronunciation significantly. This can lend to the impression that he is smiling while singing, and lean more towards a "pop" singing style when applied alongside other modes.

Range: -- (Falsetto: -) | Suggested Combinations: Warm, Passionate

The softest vocal mode, "Gentle", mellows out ASTERIAN's voice significantly, warming his tone while also creating a pleasant breathiness that can be applied to many different situations. In smaller amounts, "Gentle" can soften most other vocal modes.

Range: -- (Falsetto: -) | Suggested Combinations: Rough, Passionate, Clear

ASTERIAN's "Strained" vocal mode adds a significant degree of tension to the voice, particularly noticeable in his upper register. This can brighten up the vocal track as well as add a bit more character to the piece when mixed with other modes - this mode can even be leveraged to produce raspy lines with other adjustments.

Range: -- (Falsetto: -) | Suggested Combinations: Open, Strained

The "Rough" vocal mode is a somewhat experimental mode that adds a degree of grit and power to the voice. It works best when used in combination with other vocal modes where its effect can be more subtle, but it can also create a more unique tone when used alone as well.

Range: C3-E5 (Falsetto: E4-E5) | Suggested Combinations: Passionate, Theatrical

"Open" gives the voice a much more resonant and choral sound when compared to ASTERIAN's default settings. It can be used in small amounts to round out pronunciation into a more classical style, or in large amounts to create a dramatic performance.

Range: -- (Falsetto: -) | Suggested Combinations: Warm, Gentle, Strained

The "Closed" vocal mode is the most unusual of the selection when used alone, giving ASTERIAN a nasal and mumbling quality. However, it is best used in small amounts or as a parameter to adjust the openness of other modes. Additionally, to improve mixing clarity, it is suggested that users try the separated Aspiration Output settings on the render panel to isolate aspiration.

Range: -- (Falsetto: -) | Suggested Combinations: Strained, Clear, Warm

ASTERIAN's "Passionate" vocal mode is the closest to his default tone, but adds a subtle degree of style and performance to any piece. It can generally be used to boost ASTERIAN's emotive quality and elevates the tone of most other vocal modes as a result. "Passionate" typically functions as an "ASTERIAN+" in this way.

Range: -- (Falsetto: -) | Suggested Combinations: Open, Strained, Rough

The "Theatrical" mode is the most open and operatic of the selection, with a uniquely dramatic quality that suits more intense pieces. When combined with the "Open" vocal mode, this effect can be increased further, or it can be differently adjusted for other performance styles by blending it with modes like "Gentle" or "Closed".

License Agreement

Our virtual vocalists have specific license terms to protect songwriters who use them as well as the singers who provided their voices to these projects.

  • Audio generated using the Synthesizer V ASTERIAN product may be used commercially without limit in creative works such as music, podcasts, video games, (et cetera) without securing an additional license from Eclipsed Sounds.

  • The user may never attribute audio generated using the Synthesizer V ASTERIAN product to "Eric" or "Eric Hollaway" and may only attribute generated vocals to ASTERIAN or leave them unattributed except in certain circumstances - contact Eclipsed Sounds to determine eligibility for these exceptions.

  • The user may not use audio from ASTERIAN to generate or train any other synthesized voice, such as a text to speech voice or redistributable sampler. Including audio from ASTERIAN in a re-sold sample pack is only permitted if the ASTERIAN-generated audio is mixed in with other instruments in every included sample, and cannot be isolated to be used on its own.

  • For commercial works using the Synthesizer V ASTERIAN character mascot and not the synthesized voice, derivative products may be sold without permission or profit limit by individual persons or non-business entity production groups.

The terms for ASTERIAN & our other synthesized singers are strict due to the realism & identifiability of the voice. Unlike most VSTs or synthesizer, voices can and will be recognized by the average listener. Thank you for respecting our license & helping us protect the voices of our singers.
