Altered Real-Time Pro

Overview

Altered Real-Time Pro is desktop software that sends AI-processed speech into apps through a virtual microphone. It suits people who want to clean up, transform or restore their voice during calls and games. Its broad set of voice tools is compelling, but daily processing caps and plan-specific data terms deserve close attention.

It works with microphone-input apps such as Zoom, Google Meet, Discord, Skype, WhatsApp, games and call-centre software. Support is limited to macOS and Windows, so it is not an option for mobile-only users.

Local compute processes audio on the user's machine, with voice data staying on the PC. Cloud Compute instead offloads processing to Altered servers in the US, EU or India and costs $2 per hour of daily quota per month. That can provide a remote processing option, but it is an additional usage cost.

Key features

• Isolate suppresses noise and competing speakers, making it the broadest fit for callers who need clearer speech. It is included even on the free plan.
• Voice Skins change vocal identity. The free tier's four daily skins are a useful taste, while the $5 plan unlocks all skins.
• Accent Translation changes accents and is included in Call Center plans. Effects are designed around 135 ms algorithmic latency; actual latency varies with model, CPU, audio settings and processing cores, so the figure is not a guarantee of end-to-end responsiveness.
• Euphonia provides models for dysphonia and voice disfluencies. It is available on Euphonia plans, including a discounted option, rather than the basic Voice Skins tier.

Enterprise adds team invitations, seat assignment, usage statistics and charts, billing controls and version management. Its plan includes priority support, usage analytics, on-device or on-premise BYOC compute, Altered-hosted compute and SLA-backed uptime. Listed input languages include Indian-English, Filipino-English, LATAM-English, Slavic-English and African-English.

Pricing

• Free — free: 20 minutes of processing per day, Isolate models for speech enhancement, four Voice Skins every day and multi-seat account management. It suits occasional use, but the daily cap and limited skins constrain regular callers.
• Voice Skins — $5 a month (billed monthly, excluding tax): 120 minutes per day, all Voice Skins, all Isolate models and multi-seat account management. It is the most economical paid choice for voice changing and noise suppression, but does not include Accent Translation or Euphonia models.
• Call Center (discounted) — $8 a month (billed monthly, excluding tax): unlimited processing, Accent Translation models, all Voice Skins and Isolate models, and multi-seat account management. The 33% discount comes with consent to use anonymized voice data to improve AI models.
• Euphonia (discounted) — $8 a month (billed monthly, excluding tax): unlimited processing, Euphonia models for dysphonia and voice disfluencies, all Voice Skins and Isolate models, and multi-seat account management. It carries the same 33% discount and anonymized-data consent requirement.
• Call Center — $12 a month (billed monthly, excluding tax): unlimited processing, Accent Translation models, all Voice Skins and Isolate models, and multi-seat account management. It is the non-discounted route for callers needing accent translation without the discounted plan's data-use consent.
• Euphonia — $12 a month (billed monthly, excluding tax): unlimited processing, Euphonia models for dysphonia and voice disfluencies, all Voice Skins and Isolate models, and multi-seat account management. It fits users who need restoration models and prefer not to accept the discounted plan's consent condition.
• Enterprise — custom pricing: priced per seat, with all Accent Translation models, all Voice Skins, priority support, usage analytics, compute options and SLA-backed uptime. It is aimed at organizations that need seat-based administration and service commitments.

Standard subscriptions state that voice data never leaves the device. The privacy policy says Altered uses commercially acceptable means to protect personal data but cannot guarantee absolute security.

Platforms

Real-Time Pro runs on macOS and Windows. Its virtual microphone is designed for desktop apps that accept microphone input, rather than mobile calling workflows.

Who it's for

It is a strong fit for desktop callers, streamers and call-centre teams seeking live noise suppression, voice identity changes or specialized accent and voice-restoration processing. The free plan works for light daily use; frequent users should compare its 20-minute cap with the paid tiers. Mobile users, people needing more than 120 minutes daily without choosing an unlimited plan, and anyone unwilling to consent to anonymized voice-data use should avoid the discounted subscriptions.

Pros and cons

• Pros: One virtual microphone can serve many communication and gaming apps, and Isolate is available on the free tier.
• Pros: Specialized Accent Translation and Euphonia models have dedicated unlimited plans, while Enterprise adds seat controls, analytics and SLA-backed uptime.
• Cons: Free processing is capped at 20 minutes per day, and the $5 tier at 120 minutes per day; regular longer sessions require an unlimited plan.
• Cons: Discounted plans require consent to anonymized voice data use for AI improvement, while mobile platforms are unsupported.

Alternatives

For a broader comparison, see AI Voice Isolators, Game Voice Changers and Voice Changer Software.

AudioShake is a better fit when the task is separating audio stems or editing lyrics: its free plan starts with 200 credits, MP3 export and files up to 10 minutes. LALAL.AI is another option for uploaded-audio separation, with a free relaxed queue allowance of 10 minutes and 200 MB per file, though full downloads are unavailable on its Starter tier.

VocalDrop offers free desktop vocal isolation with no track limits, watermark, account or feature paywall. AIVoiceSeparator is a web and API alternative for song processing, with three free songs per month when signed in and full Studio quality.

Demixr provides a web-based free tier for uploaded audio, capped at 10 minutes per month and 10 MB per upload, with queued processing and no WAV downloads. Denoise is a mobile alternative for importing and denoising audio; its free tier allows previewing before saving or exporting requires Pro.

Vocly is an Android voice-isolation option with ads and separation, mixer, karaoke and stem-library features on its free plan. Sencial API is an API-only alternative, with a free allowance of 10 minutes of processing per month.

Verdict

Choose Altered Real-Time Pro if you need live voice processing across desktop communication apps, particularly for its combination of Isolate, Voice Skins and dedicated Accent Translation or Euphonia plans. Its main advantage is putting those distinct tools behind one virtual microphone; its daily limits at lower tiers and discounted-plan data consent are the reasons to look elsewhere or pay more.
