Waves H-Delay hybrid delay plug-in: features and spec-based rating

Waves’ H-Delay is a hybrid delay that can make a wide range of delay-based effects, such as echo, tape delay, chorus, flanger and vibrato. You can choose from four analog textures or a clear digital sound, and match lengths of 1 to 3500 milliseconds to the tempo.

A delay delays a sound and repeats it, like an echo. You use it to add width and rhythm to vocals and guitars.

In this article we compare H-Delay with 10 delay plug-ins and rate how well it serves its purpose on three criteria. The basis is official manufacturer information.

Summary

Among the 10 delay plug-ins, H-Delay is rank A. The ranks run S, A, B and C, and A is second from the top. Averaging the scores for each criterion (out of 5, with the one criterion that matters most for the purpose counted double) gives 3.8.

Strengths

• Tone character (4 points): you can choose the tone of the repeats, from warm tape style to clear sound.
• Easy to blend (4 points): you can shape the repeats with filters and so on so they do not get in the way of a vocal.

Who it suits: people who want everything from a standard echo to wobble effects in one plug-in.

Main features of H-Delay

Four analog types and digital

You can choose from four analog textures and a modern digital sound. There are also lo-fi settings, and the manufacturer explains that you can make everything from a clean echo to an aged one in one plug-in.

Wobble effects built from the delay

Using the delay as the base, you can make a wide range of effects, such as chorus, flanger, vibrato, doubling, slapback and self-oscillating feedback.

A filter to shape the tone

There is a filter that shapes the tone of the delayed sound. You can use it to narrow the band so the echo does not get in the way of the singing.

MIDI learn and phase adjustment

Every control has MIDI learn, so you can move the knobs from external equipment. There is also a phase adjustment that can be set separately for left and right.

Where it is useful

• Adding a tempo-matched echo to a vocal
• Adding the thickness of doubling with a short setting
• Adding an echo with vibrato to a guitar

Rating by criterion

Tone character: 4 / 5

We check whether you can choose the tone of the repeats, such as the warmth of tape and analog gear.

You can choose from four analog textures or a modern digital sound. The manufacturer explains that it can also make the sound of a tape delay.

Rhythm and width: 3 / 5

We check whether you can make rhythm and width, such as repeats that bounce left and right or repeat several times at different intervals.

The delay length is 1 to 3500 milliseconds and can be synced to the tempo. We could not confirm any listing of ping-pong or multiple taps.

Easy to blend: 4 / 5

We check whether you can adjust the repeats so they do not get in the way of the vocal (for example, making them quieter while singing).

There is a filter that shapes the tone of the delayed sound, and modulation (chorus, vibrato and so on) that can be synced to the tempo.

How we score (Delay plug-ins)

Criterion	Basis	5 pt	4 pt	3 pt	2 pt	1 pt
Tone character	Warmth that blends with a vocal, and the choice of coloration	Choose from the styles of many vintage units	Tape-style sound plus other coloration to choose from	Either tape-style or vintage-style	Clear digital sound only	—
Rhythm and width	Ping-pong, multiple taps, tempo sync and so on	Multi-tap rhythm editing and ping-pong, or more	Multiple taps and ping-pong	Either ping-pong or tempo sync	—	Not mentioned on the official page
Easy to blend	Controls that keep it from getting in the way of a vocal	Ducking and a filter for the delayed sound	Two or more controls, such as a filter and saturation	One control	—	Not mentioned on the official page

Each criterion is scored from 1 to 5 on how well the product serves one goal: adding depth and lingering tails to a vocal. Scores follow the conditions in the table above, and the rank is based on an average in which "Tone character" counts double. The basis is official manufacturer information. Sound quality and CPU load are not measured, so they are not scored; reviews from trade magazines are introduced in the articles for reference. Price is not part of the score. Features that cannot be confirmed from the manufacturer's or a retailer's description are scored as if absent. The "OBS (streaming)" column in the table shows whether the official page lists the VST2 format that the streaming software OBS Studio can use (○). OBS does not support the VST3 format. It is not part of the score.
