Mono Audio (Accessibility Audio & Visual) App Store Listing in Simplified Chinese — 单声道音频 & 单耳收听 zh-Hans Copy
Your en-US listing markets Mono Audio — Apple's built-in accessibility setting under Settings → Accessibility → Audio & Visual → Mono Audio — where iOS combines left and right stereo channels into both ears so listeners who use one ear still hear the full audio mix — but the China App Store product page still shows English title, subtitle, description, and caption lines.
Mono Audio downmixes stereo into a combined channel — not left-right Balance volume sliders (平衡), not Closed Captions + SDH media caption tracks (隐藏式字幕), not Live Caption real-time speech subtitles (实时字幕), not Live Listen remote microphone streaming (实时收听), not Hearing Devices MFi hearing-aid pairing, not Headphone Accommodations headphone EQ (耳机调节), not Background Sounds ambient loops, not Music Haptics rhythm vibration, not Sound Recognition or Name Recognition alerts, not a generic Spoken Content hub paragraph, and not Dynamic Type or display text-size toggles.
Mentioning Mono Audio on your US page does not auto-fill a Simplified Chinese (zh-Hans) localization row.
AppLocale rewrites paste-ready zh-Hans listing fields that describe your existing single-ear listening and 单声道音频 story — not AVAudioEngine downmix engineering, not audio session routing code, not screenshot design.
Listing copy only — we do not implement Mono Audio in your app, we do not guarantee rank, and we do not invent reviews or metrics.

Western indie iOS and iPadOS developers — US, UK, EU, Canada, Australia — who:
Already ship or market an app whose buyers rely on Mono Audio — audio, podcast, meditation, accessibility, or hearing-assist apps that pair with iOS stereo-to-mono downmix, or gallery frames that show Settings → Audio & Visual → Mono Audio toggles
Market Mono Audio, stereo-to-mono, single-ear listening, hear full mix in one ear, or 单声道音频 / 单耳收听 / 左右声道合并 / 辅助功能 / 音频与视觉 on the en-US product page and in screenshot galleries
Finished mono-downmix-aware or single-ear listening UX in the binary — not looking for AVAudioEngine stereo-downmix or audio session routing engineering help here
Enabled the China App Store but the zh-Hans row is empty, machine-translated, or still English on Mono Audio gallery frames
Need paste-ready Connect text — not an engineer for audio routing APIs, not a designer to re-export every mono-audio screenshot from scratch
Mono Audio engineering vs zh-Hans listing copy — two different jobs
US/EU indie teams conflate mono-downmix capability with storefront language. iOS Settings and App Store Connect actually separate them:
Mono Audio on the device — when enabled under Settings → Accessibility → Audio & Visual → Mono Audio, iOS combines left and right stereo channels into both ears so single-ear listeners hear the full mix. System accessibility behavior — outside AppLocale scope.
AVAudioEngine downmix & mono routing in your app — custom code that detects system Mono Audio preferences, downmixes stereo tracks, or routes combined channels through your player. Engineering inside the binary — not listing rewrite.
Mono Audio marketing on the product page — description paragraphs, subtitle positioning, keywords, promotional text, and screenshot overlays that tell buyers your app supports Mono Audio, stereo-to-mono, or single-ear listening workflows. Connect text fields — this page.
Pricing and Availability → China — makes the app downloadable on the China storefront. Separate from language rows.
App Store tab → Chinese (Simplified) localization — independent row for title, subtitle, keywords, description, promotional text, and screenshot caption lines. Empty or English here means China buyers see English fallback regardless of how strongly your US listing markets Mono Audio.
An app that ships mono-downmix-aware playback in the binary and a localized China listing are both valuable — neither replaces the other. AppLocale covers how you describe Mono Audio and single-ear listening on the store page, not whether your player downmixes stereo inside the app.
What Apple Mono Audio is — and what your listing may claim
Apple ships Mono Audio under Settings → Accessibility → Audio & Visual → Mono Audio. When enabled, the device combines left and right stereo channels into both ears. Western indie listings often show one or more of these surfaces on the US product page. AppLocale covers paste-ready zh-Hans copy for whichever your screenshots and description already claim:
Mono Audio toggle (单声道音频) — master switch that downmixes stereo into a combined channel for single-ear listening. Gallery frames may show the Audio & Visual settings branch or a "Works with Mono Audio" badge.
Single-ear listening workflows (单耳收听) — marketing that emphasizes hearing the full left-and-right mix when using one earbud, one hearing aid, or one side of wired headphones. Screenshot overlays often show one-ear listening demos or before/after stereo-vs-mono comparisons.
Channel combining (左右声道合并) — when your English listing explains that both stereo channels play through each ear so no audio information is lost for one-ear listeners. zh-Hans copy should use 左右声道合并 only when your US page already claims channel combining — not as a generic "better audio" synonym.
Mono-downmix-aware playback in your app — in-app audio players, podcast episodes, meditation sessions, or lesson modules that respect system Mono Audio when stereo content plays. Screenshot overlays often show mono-downmix badges on player UI or settings walkthroughs.
Your gallery may lead with a Mono Audio settings toggle on one frame and an in-app player with single-ear listening callouts on the next. zh-Hans caption lines should name the correct surface per frame — a Mono Audio toggle is not a Balance slider, not a Headphone Accommodations EQ graph, and not a Live Listen microphone badge unless that is what the screenshot shows.
Mono Audio listing copy vs Balance, Hearing, and other audio guides
Several shop guides cover adjacent Apple Accessibility audio features under Audio & Visual and Hearing. This page covers Mono Audio and stereo-to-mono marketing on listing metadata — not engineering, not unrelated category copy:
Mono Audio and stereo-to-mono channel combining (this page) — downmixing left and right stereo into both ears, single-ear listening, hear full mix in one ear, and 单声道音频 / 单耳收听 / 左右声道合并 on gallery frames and in description paragraphs.
Balance left-right volume sliders (different — contrast only) — shifts emphasis between left and right channels without downmixing stereo to mono — 平衡. Lives under the same Audio & Visual branch but is a different buyer story from 单声道音频. See Balance listing guide — left-right channel volume, not stereo channel downmix.
Headphone Accommodations & audio EQ (different) — headphone tuning presets, amplify soft sounds, frequency EQ — 耳机调节. See Headphone Accommodations listing guide — headphone frequency compensation, not stereo channel downmix.
Spatial Audio & immersive sound (different) — Dolby Atmos, head-tracked 3D audio — 空间音频. See Spatial Audio listing guide — immersive positioning, not mono-downmix accessibility.
Closed Captions + SDH (different) — embedded media caption tracks — 隐藏式字幕. See Closed Captions listing guide — caption display on video, not audio channel routing.
Live Caption real-time speech subtitles (different) — on-device speech-to-text captions — 实时字幕. See Live Caption listing guide — generated subtitles, not stereo downmix.
Live Listen & remote microphone streaming (different) — iPhone as a directional microphone streamed to AirPods. See Live Listen listing guide — conversation amplification, not channel combining.
Hearing Devices & MFi hearing aids (different) — Made for iPhone hearing-aid pairing and control. See Hearing Devices listing guide — hardware pairing workflows, not mono-downmix toggles.
Hearing Aid Compatibility / HAC mode (different) — telecoil-compatible phone calls and HAC mode under Settings → Accessibility → Hearing — not stereo channel downmixing. See Hearing Aid Compatibility listing guide — HAC optimizes call audio; Mono Audio combines stereo channels for single-ear playback.
Background Sounds & Music Haptics (different) — ambient loops for focus and haptic rhythm vibration — 背景音, 音乐触感. See Background Sounds listing guide or Music Haptics guide — not stereo-to-mono marketing.
Sound Recognition & Name Recognition (different) — environmental sound alerts and called-name notifications. See Sound Recognition listing guide — alert workflows, not audio routing.
You can localize the title and still leave every Mono Audio screenshot overlay and single-ear listening demo paragraph English-only. Buyers then see a Chinese name with English "Mono Audio" badges — a mismatch that reads like half-finished localization. See also China App Store still shows English when entire rows fall back.
Where English Mono Audio copy shows on the China product page
Western indie teams often market single-ear listening or mono-downmix compatibility on the US page but leave storefront Mono Audio marketing English-only. On the China storefront, English surfaces in places buyers actually read:
Screenshot overlay badges — "Mono Audio", "Single-ear listening", "Stereo to mono", "Hear full mix in one ear", "Channel combining" on gallery frames showing player UI, settings toggles, or one-ear listening demos
Description paragraphs — English value props about unilateral hearing loss, single-earbud workflows, or stereo-downmix accessibility that China readers skim past
Subtitle and keywords — English-only rows miss China Search intent for 单声道音频, 单耳收听, or 左右声道合并 when buyers filter for audio-accessibility apps
Promotional text — 170-character field still pitching Mono Audio in English above the description
Mixed page — Chinese description pasted once but Mono Audio screenshot captions and subtitle still English — reads unfinished next to localized competitors
Formal machine translation — stiff 翻译腔 that conflates 单声道音频 (Mono Audio) with 平衡 (Balance), 耳机调节 (Headphone Accommodations), or 空间音频 (Spatial Audio) when your English source only claimed stereo-to-mono downmix
Better zh-Hans listing copy helps single-ear and audio-accessibility buyers understand your Mono Audio story before install. It does not replace AVAudioEngine downmix implementation, audio session routing work, or Apple's review decisions — and it does not require you to re-shoot an entire audio screenshot gallery to mention 单声道音频 in text.
What AppLocale delivers for Mono Audio apps on zh-Hans
This SKU is a listing rewrite scoped to Mono Audio and single-ear listening marketing — paste-ready fields you copy into App Store Connect:
Name (title) — zh-Hans app name within Connect character limits when your English title does not signal mono-downmix accessibility to China searchers
Subtitle — concise benefit line that can reference Mono Audio or single-ear listening without stuffing raw English badge text
Keywords — zh-Hans search terms buyers use for 单声道音频, 单耳收听, 左右声道合并, and audio-accessibility apps in your category
Description — long listing body with clear zh-Hans paragraphs on Mono Audio workflows you already claim — without English-only "Mono Audio" jargon
Promotional text — when you include the 170-character promo field in scope
Screenshot overlay / caption lines — short zh-Hans text on gallery images that show Mono Audio toggles, single-ear listening demos, or stereo-to-mono player frames ("单声道音频", "单耳也能听全混音", "左右声道合并")
English alignment — matching en-US field notes when both storefronts must stay consistent on Mono Audio promises
We map deliverables to the fields you actually use. Send every English overlay line and description paragraph that mentions Mono Audio, stereo-to-mono, single-ear listening, or channel combining — we deliver counted strings that fit Connect limits. We rewrite what you already claim on the US page; we do not invent mono-downmix features your app does not describe.
Mono Audio-specific listing vocabulary — what translates differently
Single-ear listening marketing on App Store pages uses vocabulary general utility guides rarely cover. zh-Hans copy should reflect how Chinese buyers describe Mono Audio in iOS Settings — not a literal paste of US marketing:
Official Settings vocabulary
Apple's zh-Hans Settings UI uses 单声道音频 for Mono Audio under 辅助功能 → 音频与视觉 (Audio & Visual). Related commerce phrasing includes 单耳收听 (single-ear listening), 左右声道合并 (left-right channel combining), and 音频与视觉 when your gallery shows the Audio & Visual settings branch — not as a standalone hub title. Listing copy should mirror that vocabulary — not generic "better sound" or medical claims.
Mono Audio vs Balance
Balance shifts volume emphasis between left and right channels — 平衡 — without downmixing stereo to mono. Mono Audio combines both channels so each ear hears the full mix — 单声道音频. zh-Hans listing copy should not imply left-right volume sliders when your English source only shows a Mono Audio toggle or stereo-to-mono player demo.
Mono Audio vs Headphone Accommodations and Spatial Audio
Headphone Accommodations covers frequency EQ and amplify soft sounds — 耳机调节. Spatial Audio covers immersive head-tracked Dolby Atmos — 空间音频. Mono Audio covers channel downmix for single-ear listeners — 单声道音频. If your English gallery shows an EQ slider graph or a 3D sound badge, do not paste Mono Audio vocabulary onto those frames.
Mono Audio vs Closed Captions and Live Caption
Closed Captions displays embedded caption tracks on media — 隐藏式字幕. Live Caption generates real-time speech subtitles — 实时字幕. Mono Audio routes combined stereo audio to ears — 单声道音频. Caption and audio-routing claims use different Connect string families.
Subtitle and keyword packing
The 30-character subtitle and 100-character keyword field need mono-downmix search terms Chinese buyers type — see Simplified Chinese keywords & subtitle for field mechanics. Terms like 单声道音频, 单耳收听, and 左右声道合并 each signal different intent from 平衡 or 耳机调节 keywords.
Caption lines vs burned-in badges
Marketing screenshot overlays you control — "Mono Audio" headlines on gallery frames showing single-ear listening demos — are separate caption fields or burned-in PNG text. See Screenshot captions in Simplified Chinese for caption-field mechanics when overlays are editable in Connect.
Why English-only Mono Audio copy hurts China storefront conversion
Single-ear and audio-accessibility purchasers browsing the China App Store evaluate mono-downmix claims in the first scroll. Common failure modes when only en-US is filled:
Trust gap — Chinese word-of-mouth recommends a "single-ear listening" audio app; buyer taps through and sees English "Mono Audio" with no zh-Hans context
Localized listing, English badges — description promises Chinese 单声道音频 support; screenshot overlays still "Stereo to mono" at the worst moment
Search intent miss — buyers search 单声道音频 or 单耳收听; English-only keywords miss intent even when your app ships mono-downmix-aware playback in the binary
Balance vocabulary bleed — machine-translated 平衡 appearing in zh-Hans copy when English source only claimed stereo downmix, confusing buyers who wanted channel combining not left-right sliders
Headphone Accommodations vocabulary bleed — 耳机调节 appearing when English source showed Mono Audio toggles, not EQ presets
Competitor contrast — rivals with native zh-Hans Mono Audio and 单声道音频 copy look more serious about China buyers who care about 无障碍 and single-ear listening
Clearer zh-Hans Mono Audio marketing reduces confusion on the product page. It does not replace AVAudioEngine downmix implementation or in-app audio routing engineering — and it is not a substitute for single-ear positioning your app does not claim.
Machine translation is fine for internal drafts. Finished Mono Audio strings need idiomatic zh-Hans that states what channel-combining scope you claim — while keeping accurate separation from Balance, Headphone Accommodations, and Closed Captions marketing. AppLocale rewrites by hand; we do not deliver raw Google Translate or LLM output as finished copy.
What good zh-Hans Mono Audio listing copy looks like
Single-ear listening copy appears on screenshot galleries and in description skims. Strong Chinese strings lead with the benefit and state scope plainly:
Overlay: "单声道音频，单耳也能听全左右声道" — Mono Audio frame with clear benefit line
Description paragraph: plain zh-Hans list of Mono Audio workflows you ship — stereo-to-mono downmix, single-ear listening, channel combining — matching what you actually describe on the US page
Subtitle: "单声道音频" or "单耳收听全混音" within the ~30-character cap
Keywords: include 单声道音频 / 单耳收听 / 左右声道合并 only when accurate — do not keyword-stuff 平衡 or 耳机调节 if you only market Mono Audio
Honest scope — do not claim Headphone Accommodations EQ in Chinese if your app only ships mono-downmix player demos
zh-Hans and en-US strings can differ in length and structure when the underlying Mono Audio story is the same — avoid mirroring English comma-heavy promo lines character-for-character.
