Was ist Audiolatenz? Millisekunden, Ursachen und Lösungen

Audiolatenz ist die Zeit zwischen einer Aktion und dem hörbaren Ton. Dieser Ratgeber erklärt Messwerte, Ursachen und wirksame Schritte zur Verringerung.

Latency in msAcceptable delayCausesHow to reduce it
Kurzantwort

Audiolatenz wird in Millisekunden (ms) gemessen. Unter 20 ms wirkt meist unmittelbar, 20–50 ms ist oft gut nutzbar, 50–100 ms wird bemerkbar und über 100 ms stört häufig Gaming, Monitoring, Gespräche und Lippensynchronität.

0–20 msExcellent

Usually feels immediate for playing, monitoring and competitive use.

20–50 msGood

Often acceptable for casual gaming, calls and general listening.

50–100 msNoticeable

Timing starts to feel soft; speech and video may look slightly detached.

100+ msDistracting

Echo, late feedback and obvious lip-sync errors are common.

Definition

Was Audiolatenz wirklich bedeutet

Die Gesamtverzögerung entsteht beim Aufnehmen, Verarbeiten, Übertragen und Wiedergeben. Ausgangslatenz betrifft Video und Gaming; Round-Trip-Latenz umfasst zusätzlich den Eingang.

Output latency

Time from a device or app sending audio until your headphones or speakers reproduce it.

Input latency

Time from a microphone or instrument entering the system until software receives it.

Round-trip latency

Input delay plus processing and output delay—the number performers usually feel.

A/V sync offset

Difference between the visible event and the sound; test it with the audio sync tool.

Thresholds

Wie viel Audiolatenz ist akzeptabel?

Es gibt keinen perfekten Wert für jeden Zweck. Passives Hören verträgt größere Puffer, Live-Monitoring und schnelle Reaktionen dagegen nicht.

Music recording

Aim below 20 ms round trip; many performers prefer roughly 10 ms or less.

Competitive gaming

Lower is better; below 30–40 ms audio output helps cues feel connected.

Video and streaming

Lip sync is usually comfortable when offset stays within roughly 40–60 ms.

Calls and meetings

Small local device delay is fine, but network delay adds to the conversation gap.

Signal chain

Was verursacht Audioverzögerung?

Verzögerung summiert sich entlang der Signalkette: Funkcodec, Puffer, Effekte, Systemmixer, TV-Verarbeitung oder Netzwerk.

Wireless transmission

Bluetooth encoding, radio transmission and decoding add buffering.

Audio buffers

Larger buffers prevent glitches but increase delay.

Software processing

Noise removal, spatial audio, EQ, plugins and resampling need time.

Display processing

TV motion smoothing and video pipelines can move pictures later than sound.

Fixes

So verringern Sie Audiolatenz

Ändern Sie jeweils nur einen Teil und messen Sie erneut. So erkennen Sie wirksame Einstellungen, ohne Stabilität gegen Knackser einzutauschen.

  1. Measure a baseline

    Run the main audio latency test with the same device, browser and connection you normally use.

  2. Use a wired path

    For recording or rhythm-sensitive work, wired headphones and a direct audio interface are the most reliable shortcut.

  3. Lower the buffer carefully

    Reduce buffer size in the DAW or audio app until delay improves without crackles.

  4. Disable unnecessary processing

    Temporarily turn off spatial audio, enhancement suites, noise suppression and heavy plugins.

  5. Match the media path

    Use game/low-latency mode on earbuds or TVs and avoid routing audio through extra devices.

  6. Retest and record the result

    Compare the new measurement with the baseline instead of judging from memory.

Measurement

Audiolatenz zuverlässig messen

Browsertests liefern eine praktische Schätzung. Halten Sie die Bedingungen konstant, wiederholen Sie den Test und nutzen Sie den Median.

Repeat trials

Use at least five attempts and ignore accidental taps or obvious outliers.

Keep conditions fixed

Do not switch codec, output device, browser tab or enhancement settings between runs.

Test the real setup

Measure the TV, console, earbuds or interface exactly as you normally connect it.

Separate device and network lag

Audio hardware latency and internet latency are different problems.

FAQ

Häufige Fragen zur Audiolatenz

Is 100 ms audio latency bad?

For passive listening it may be tolerable, but 100 ms is clearly noticeable for gaming, live monitoring, calls and lip sync.

Can Bluetooth audio have zero latency?

No practical Bluetooth path is truly zero-latency. Low-latency modes and newer codecs can reduce delay, but the phone, codec and earbuds all matter.

Why do I hear my voice late in headphones?

You are hearing round-trip latency: microphone input, software processing and headphone output delay combined.

Does a faster internet connection reduce audio latency?

It can reduce network delay in calls or cloud gaming, but it does not fix local Bluetooth, buffer or device-processing latency.

What is the difference between latency and lag?

They are often used interchangeably. Latency is the measurable delay; lag is the user-visible or audible effect of that delay.
