はじめに

どうやって使うの？

Snore Timelineはシンプルに設計されています。アプリを開いて録音ボタンを押すと、睡眠中の音を追跡できます。電話をベッドサイドの30〜60cm程度の位置に置き、できれば充電してください。アプリは一晩中録音し、音声をリアルタイムで処理します。

何を検出するの？

オンデバイスAIで以下の睡眠音を検出・分類します：

• Snoring — The primary focus, detected at frequencies mostly between 50Hz-3kHz. Each detection is marked on the timeline with its volume level.
• Gasps — Sudden intake of breath sounds, often associated with breathing disruptions
• Coughs — Coughing during sleep, tracked separately from snoring
• Sleep talking — Speech, whispers, and babbling sounds
• Breathing — Regular breathing patterns used for both disruption detection and sleep stage classification

AppleのSound Analysisフレームワークを使い、すべてデバイス上でリアルタイム処理されます。

アカウントは必要？

いいえ。Snore Timelineにはアカウントやログイン、クラウドサービスはありません。すべてデバイス上でローカルに動作します。

検出の仕組み

リアルタイムAI分析

Unlike apps that sample audio periodically, Snore Timeline analyzes your audio continuously in real-time using Apple's on-device sound classification. Every sound is processed as it happens—no data is skipped or sampled.

信頼度のしきい値

The AI assigns a confidence score to each detected sound. The app uses different thresholds depending on the sound type and whether you're actively using the phone or it's running in the background (when you're actually sleeping). This helps reduce false positives while maintaining accuracy.

デシベル計測

Sounds are measured in decibels (dB SPL), with the app capable of measuring up to 105 dB. Think of it like a volume meter—the higher the number, the louder the sound. The app tracks both peak and average decibel levels for each episode.

タイムラインの見方

インタラクティブなタイムライン表示

Your entire night is displayed on a scrollable, zoomable timeline. You can navigate through your sleep session to see exactly when sounds occurred.

時間スケール

The timeline supports multiple zoom levels:

• 1-second intervals — Most detailed view, each tick represents 1 second
• 5-second intervals — Detailed view for examining specific episodes
• 1-minute intervals — Good for reviewing specific periods
• 10-minute intervals — Overview of sleep patterns
• 1-hour intervals — Full night at a glance

Tip: Hold down the zoom button to quickly zoom all the way in or out—no need to tap multiple times.

夜の切り替え

Swipe left or right on the Nightly Summary screen to move between different nights. The same gesture works on the 週間サマリー screen to navigate between weeks.

カレンダー表示

Use the calendar to jump directly to any recorded night. Nights with recordings are highlighted so you can easily find your data.

タイムライン上の睡眠ステージ表示

If sleep stages were detected, you'll see colored background bands on your timeline indicating which stage you were in at each point during the night. This makes it easy to correlate snoring episodes with specific sleep stages.

週間サマリー

The 週間サマリー screen shows trends across multiple nights, allowing you to track:

• Episode count trends — See if your snoring is increasing, decreasing, or staying consistent
• Average volumes — Track whether your snoring is getting louder or quieter over time
• Total recording time — How much sleep you're getting each night
• Week-over-week comparisons — Compare the current week to previous weeks

This helps you identify patterns and see if lifestyle changes (sleep position, weight loss, avoiding alcohol, etc.) are making a difference.

エピソードとイベント

いびき信号とは？

Every time the app detects a snoring sound, it counts as one "snore signal." More signals means more snoring activity during that period.

エピソードとは？

An episode is a group of snore signals that happen close together in time. When the app detects snoring, it creates an episode. If no snoring occurs for 30 seconds, that episode ends. The next time snoring is detected, a new episode begins.

エピソードの詳細

Each episode shows:

• Duration — How long the episode lasted
• Snore count — Total number of snore signals
• Peak volume — Loudest moment in decibels
• Average volume — Overall loudness level
• Event breakdown — Counts of snoring, gasps, coughs, and sleep talking
• Plain-English summary — A description like "Heavy snoring for over 20 minutes, with a breathing disruption"

エピソードの説明

The app automatically generates descriptions based on the episode characteristics:

• Volume levels: Faint (<40 dB), Light (40-48 dB), Audible (48-56 dB), Heavy (56+ dB)
• Rhythm patterns: Rhythmic (consistent intervals), Regular (minor variations), Intermittent (stop-and-start)
• Trends: Whether snoring grew louder, faded, or stayed stable over time

呼吸中断

呼吸中断とは？

A breathing disruption is flagged when the app detects a specific pattern: audible breathing followed by extended silence, then a recovery sound. This may indicate pauses in breathing during sleep.

どう検出される？

The detection requires three conditions in sequence:

1. Baseline breathing — The app must detect audible breathing sounds for at least one minute before the silent period (11 out of 12 five-second windows must have breathing detected)
2. Extended silence — A period of complete silence lasting 10 seconds or more
3. Recovery sound — The silence is broken by a snore signal that is at least 15 dB louder than the average volume during the silent period

タイムラインのマーカー

Breathing disruptions appear as subtle gray-blue markers on your timeline, making it easy to spot patterns throughout the night.

重要な注意事項

This is audio analysis only—not a medical device. The app cannot diagnose sleep apnea or any other medical condition. It analyzes sound patterns, not blood oxygen levels or brain activity. If you notice frequent breathing disruptions, consider discussing the results with a healthcare professional.

睡眠ステージ

睡眠ステージとは？

Sleep Stages is a feature that estimates which sleep stage you're in at any given time throughout the night: Awake, Light Sleep, Deep Sleep, or REM (Rapid Eye Movement). These estimates appear as colored bands on your timeline and as a hypnogram chart in your nightly summary.

仕組み

The app analyzes the regularity and variance of your breathing patterns captured through the microphone. After approximately 15 minutes of recording, the algorithm establishes your personal breathing baseline. It then uses research-based thresholds to classify sleep stages:

• Deep Sleep — Steady, regular breathing with low variance
• REM Sleep — Irregular breathing patterns with high variance
• Light Sleep — Moderate breathing regularity
• 起床 — Movement, sounds, or breathing patterns inconsistent with sleep

The algorithm also considers breathing rate, snoring patterns, and time of night. Deep sleep typically occurs early in the night, while REM increases toward morning.

ヒプノグラムの見方

The hypnogram is a chart that shows your progression through sleep stages across the night. Each colored band represents 5 minutes in a particular stage:

• Orange — Awake periods
• Cyan (light blue) — Light Sleep
• Indigo (deep blue) — Deep Sleep
• Pink/Cyan — REM Sleep

You can see how many complete sleep cycles you went through, when you had the most deep sleep, and when REM sleep occurred.

ステージの分布

The nightly summary also shows the percentage of time you spent in each stage. A typical night's sleep might look like:

• 45% Light Sleep
• 20% Deep Sleep
• 27% REM Sleep
• 8% Awake

These percentages can vary based on age, health, stress levels, and other factors.

推定の精度は？

Sleep stage detection is based on published research into the relationship between breathing regularity and sleep stages. The estimates provide a useful picture of your general sleep architecture and trends over time. Research using similar audio-based methods has achieved approximately 70% accuracy when validated against polysomnography (clinical sleep studies).

Important: These are estimates from audio analysis, not clinical measurements. The app has not been validated against polysomnography and should be treated as estimates, not diagnoses. For clinical sleep analysis, consult a healthcare professional.

睡眠ステージが検出されない理由

Sleep stage detection requires audible breathing throughout the recording. If stages aren't detected:

• Your breathing may not be audible enough to the microphone
• The phone may be positioned too far away (try 1-2 feet)
• Background noise may be interfering with breathing detection
• The recording may be too short (algorithm needs ~15 minutes to establish baseline)

研究参考文献

The sleep stage classification algorithm is informed by:

• Aging Effects on Cardiac and Respiratory Dynamics in Healthy Subjects across Sleep Stages (Schumann et al., 2010) — Demonstrates that respiratory scaling exponents differ measurably between sleep stages
• Using Spectral Continuity to Extract Breathing Rate from Heart Rate and Its Applications in Sleep Physiology (Orphanides et al., 2024) — Confirms that deep sleep has the most stable and predictable breathing
• Sleep Stage Classification from Heart-Rate Variability — Audio-based sleep stage classification achieving ~70% accuracy

録音のコツ

電話の配置

Keep your phone about 1-2 feet away from you for best results. Closer means louder detection, but too far away reduces accuracy—especially for capturing breathing sounds, which must be clearly audible to be detected.

Ideal setup: Place your phone on a nightstand near your bed, plugged in for charging.

バッテリー消費

Snore Timeline is optimized for overnight recording. Most users report 20-30% battery drain over 8 hours. Keeping your phone plugged in ensures uninterrupted recording.

Bluetoothデバイス

The app supports Bluetooth audio devices including AirPods. However, for best breathing detection, the phone's built-in microphone typically provides more consistent results.

部屋の環境

For breathing disruption detection and sleep stage classification to work effectively, your regular breathing needs to be audible to the phone's microphone. If you're a very quiet breather or the phone is too far away, breathing sounds may not be detected consistently enough to establish a baseline.

睡眠ステージ検出を最適化する

To get the most accurate sleep stage estimates:

• Consistent placement — Use the same phone position each night so breathing is detected consistently
• Quiet room — Minimize background noise from fans, AC units, or outside traffic
• Full night recording — The algorithm improves over time; longer recordings (6+ hours) provide better stage classification
• Audible breathing — The phone must be close enough to pick up your breathing sounds clearly (1-2 feet is ideal)

トラブルシューティング

アプリが何も録音しなかった

The app only saves audio when it detects sleep-related sounds. If nothing was recorded:

• Check that Snore Timeline has microphone permission in Settings > Privacy > Microphone
• Make sure the phone was close enough to detect sounds (1-2 feet)
• Ensure the phone wasn't muted or in Do Not Disturb mode that might affect recording
• You may simply have had a quiet night with minimal snoring

呼吸中断が検出されない

Breathing disruption detection has strict requirements:

• Your regular breathing must be audible to the phone for at least one minute before the silent period
• The phone may be too far away to pick up breathing sounds
• The silence must last at least 10 seconds
• A recovery sound (snore, gasp) must follow that's significantly louder than the silence

検出が不正確に思える

If you're getting too many or too few detections:

• Try adjusting phone placement—closer for more sensitivity, further for less
• Background noise (fans, AC, traffic) can affect detection accuracy
• The app uses different sensitivity when in the background vs. foreground to reduce false positives from daytime sounds

ストレージがいっぱいになる

• Delete old recordings you no longer need from within the app
• Enable storage limits in settings to automatically manage space
• Switch to a lower recording quality to reduce file sizes

録音中にアプリがクラッシュまたは終了した

The app is designed to continue recording in the background. If it stopped unexpectedly:

• Make sure Background App Refresh is enabled for Snore Timeline
• Keep the phone plugged in—iOS may close background apps when battery is low
• Check that no other apps are competing for audio resources
