Your music,
expanded for the way you listen.

Every PhantomStage 5.1 conversion is customized around the source music, your surround preferences, and your playback setup. Whether you listen through a dedicated home theater, AV receiver, or compatible 5.1 system, we shape the surround field to preserve the original stereo character while adding space, depth, and presence around you.

Preserves Original Stereo

Front left and right channels remain untouched. Exactly as mixed, with no phase distortion or EQ coloring.

Adds Space & Rear Ambience

Spatial cues extracted from the original mix are diffused into rear channels. Natural, enveloping, never synthetic.

C
Subtle Center Channel

Vocals and key musical details are gently anchored in the center, adding clarity and focus without overpowering the original stereo mix.

.1
Controlled LFE/Sub

Low-frequency energy is routed cleanly to the .1 channel. Bass extension without mud or boom.

Reference Track Approval

Approve the sound before the full album is finished.

For eligible album, custom, and membership batch projects, you choose one track you know best. We convert that reference track first and send it to you for evaluation. You then complete a guided feedback form so we can fine-tune the surround balance before applying the approved direction to the full album or batch.

How the revision flow works

1. Reference preview
We convert your chosen track first so you can judge the surround treatment on your own system.
2. Guided feedback form
You approve the sound or request a controlled revision using clear adjustment options.
3. Final album adjustment
After approval, eligible albums receive a consistency pass so all tracks feel balanced together.

Revision passes are controlled fine-tuning passes based on the available adjustment form options. They are not unlimited remixing or song-by-song reconstruction.

Simple. Transparent.

All conversions are delivered as private 5.1 FLAC packages for personal use only.
Client must own the source files or have permission to request conversion.

Choose Your Listening Experience

Every PhantomStage 5.1 conversion lets you choose the overall surround presentation and low-frequency preference. There is no single correct setting — the best choice depends on the music, your system, and how immersive you want the playback to feel.

Style 01

Audiophile

Natural · Balanced · Music-First

The most faithful and restrained presentation. Audiophile mode preserves the original front stereo image as the foundation, with subtle center support, controlled LFE, and tasteful rear ambience for added space without changing the character of the music.

  • Classic rock & metal
  • Progressive music & vocal-focused albums
  • Albums you know deeply
  • Serious critical listening
Recommended Default
Style 03

Cinematic

Dramatic · Bold · Room-Filling

The largest and most dramatic PhantomStage presentation. Cinematic mode adds a stronger sense of surround presence, deeper spatial energy, and bigger room impact while still preserving the original stereo source as the core of the mix.

  • Soundtrack-style and cinematic albums
  • Symphonic & orchestral material
  • System demos and showcase tracks
  • Theater-style playback and high-impact listening
Most Dramatic

Note: All styles are designed to preserve the original stereo source in the front channels. The difference is how much center support, rear ambience, spatial width, and low-frequency weight are added during the custom 5.1 conversion.

Choose Your Low-Frequency Character

Included with every conversion. Select how much low-end weight and subwoofer presence you want in the final 5.1 FLAC.

Natural
Clean · Controlled · Music-Focused

A conservative LFE approach designed to follow the original recording closely. Natural mode adds clean low-frequency extension and subwoofer support without making the mix feel heavier than intended.

Best for

  • Critical listening & classic albums
  • Acoustic, vocal, jazz, and lighter rock material
  • Systems that already have strong bass response
Deep
Fuller · Stronger · More Physical

A deeper low-frequency presentation with more weight, body, and home theater impact. Deep mode adds stronger subwoofer presence while remaining controlled and protected against excessive boominess or clipping.

Best for

  • Rock, metal, electronic, cinematic, and live material
  • Larger home theater systems
  • Listeners who enjoy more physical bass impact
  • Demo-style or room-filling playback

Note: Both bass options use controlled LFE handling. Natural keeps the low end closer to the original stereo source, while Deep adds more physical weight for listeners who want stronger subwoofer impact.
