PHON vs Ginger Audio SPHERE Stereo

Both are monitor controllers that run on the Mac, between your DAW and your speakers. SPHERE Stereo is the entry edition of a system built for surround and immersive rooms. PHON is built for stereo only, and goes further on what a stereo mix needs. If you are looking for an alternative to SPHERE, here is what each one does and what each one lacks.

What both do

• Sit in software between your sources and your interface's outputs, before the converter.
• Switch speakers and headphones, with volume, dim and mute.
• Mono, mid and side checks.
• Calibrated listening levels you can jump back to.
• Loudness metering.
• A plugin that carries your DAW's output straight to the controller: GroundControl LINK for SPHERE, PHON Send for PHON.
• Stream Deck, MIDI control and a remote on your phone.
• macOS on Apple Silicon and Intel, and a 14-day trial.

Side by side

Where PHON goes further

Loudness compensation that follows the fader

At your calibrated reference, PHON applies nothing. Turn the volume down and it restores the low end your ears lose at that level, computed from the ISO 226 equal-loudness contours and the difference between the two levels. You can work quietly for hours and still make bass decisions that hold at full level. We found nothing like it in SPHERE. How it works.

A reference from any app, level-matched in one click

Source B can be Spotify, Apple Music, a browser or another DAW, captured as it plays. MATCH measures both sources for three seconds and sets them to the same loudness, so the louder one stops winning. Nothing to import, nothing on your master bus.

No driver in the path

PHON takes applications through Core Audio taps, which macOS provides since 14.2: no virtual audio device to select in each app, no aggregate device. Your DAW can come in through PHON Send, a plugin on your master bus.

Protection on every output

A brick-wall limiter with 1 ms lookahead and a Linkwitz-Riley safety low cut sit on each output, so a plugin that misbehaves does not reach your tweeters at full scale.

Price and licence

€69 once, two Macs, every 1.x update included. SPHERE Stereo costs about three and a half times as much for one activation, or runs as a subscription.

What PHON leaves out

PHON is a stereo controller. It has no cue output or talkback, no bass management for subwoofers, no room correction, no plugin hosting, no EUCON or OSC, and PHON Send has no AAX version. If your room needs these, SPHERE does them; if it does not, you are not paying for them.

Which one to choose

Questions

Is PHON an alternative to Ginger Audio SPHERE?

For a stereo studio on the Mac, yes. PHON switches sources, speakers and headphones, holds a calibrated volume, and adds level-matched A/B against any app, ISO 226 loudness compensation and a limiter on each output, for €69 one-time. It is not an alternative for surround or immersive work, nor if you need a cue output, talkback or bass management: SPHERE does those and PHON does not.

Does PHON have a cue mix or talkback?

No. PHON plays one output at a time, so you cannot mute your monitors and keep a separate feed going to a performer's headphones, and it has no talkback input. If you record artists from the control room, SPHERE's dedicated cue output and talkback input, or your interface's own mixer, do that job.

Can I use PHON with a subwoofer?

PHON's outputs are stereo pairs with no crossover and no bass management. A subwoofer that does its own crossover, or speakers that manage their own low end, work as usual after your interface. If you want the controller itself to split the low end between speakers and up to four subwoofers, SPHERE does it.

Does PHON need a virtual audio driver?

No. On macOS 14.2 and later PHON captures any application directly through Core Audio taps, with no driver, no kernel extension and no aggregate device. Your DAW can also reach PHON through the PHON Send plugin, a hardware input or a virtual device. SPHERE installs its own virtual audio devices, which applications play into.

Can PHON take my DAW's master bus directly?

Yes. PHON Send, a VST3 and Audio Unit plugin included with PHON, goes on your master bus and makes that track a source in PHON. There is no AAX version.

Can I control PHON from a Stream Deck?

Yes. The PHON plugin for Stream Deck puts outputs A, B and C, mid, side, flip L/R, mute, dim, loudness compensation, source and level on its keys, and the volume on the dial of a Stream Deck +, pressed to mute. Each key lights when PHON is in that state. It needs the Stream Deck app 7.1 or later and talks to PHON on your own Mac. PHON also takes any MIDI controller through MIDI Learn, the numeric keypad and a web remote in any browser. It does not support EUCON or OSC.

Does PHON work with AES, ADAT or network audio interfaces?

PHON uses any Core Audio device as a source or an output. An interface that reaches your speakers over AES, ADAT or a network audio protocol appears to PHON as an ordinary device, and you choose which channel pair each of the three outputs uses.
