La latencia se mide en milisegundos (ms). Menos de 20 ms suele sentirse inmediato; 20–50 ms funciona bien en muchos casos; 50–100 ms ya se nota; más de 100 ms suele afectar juegos, monitorización, llamadas y sincronización labial.
Usually feels immediate for playing, monitoring and competitive use.
Often acceptable for casual gaming, calls and general listening.
Timing starts to feel soft; speech and video may look slightly detached.
Echo, late feedback and obvious lip-sync errors are common.
Qué significa realmente la latencia de audio
La latencia total aparece mientras el sonido se captura, procesa, transmite y reproduce. La latencia de salida afecta a vídeo y juegos; la de ida y vuelta también incluye la entrada del micrófono.
Time from a device or app sending audio until your headphones or speakers reproduce it.
Time from a microphone or instrument entering the system until software receives it.
Input delay plus processing and output delay—the number performers usually feel.
Difference between the visible event and the sound; test it with the audio sync tool.
¿Cuánta latencia de audio es aceptable?
No existe una cifra perfecta para todo. La reproducción pasiva tolera más búfer, mientras que tocar, cantar o reaccionar en tiempo real exige menos retraso.
Aim below 20 ms round trip; many performers prefer roughly 10 ms or less.
Lower is better; below 30–40 ms audio output helps cues feel connected.
Lip sync is usually comfortable when offset stays within roughly 40–60 ms.
Small local device delay is fine, but network delay adds to the conversation gap.
¿Qué causa el retraso de audio?
El retraso se acumula en toda la cadena: códec inalámbrico, búfer, efectos, mezcla del sistema, procesamiento del televisor o red.
Bluetooth encoding, radio transmission and decoding add buffering.
Larger buffers prevent glitches but increase delay.
Noise removal, spatial audio, EQ, plugins and resampling need time.
TV motion smoothing and video pipelines can move pictures later than sound.
Cómo reducir la latencia de audio
Cambia una parte de la cadena cada vez y vuelve a medir. Así sabrás qué ajuste ayuda sin cambiar estabilidad por chasquidos.
- Measure a baseline
Run the main audio latency test with the same device, browser and connection you normally use.
- Use a wired path
For recording or rhythm-sensitive work, wired headphones and a direct audio interface are the most reliable shortcut.
- Lower the buffer carefully
Reduce buffer size in the DAW or audio app until delay improves without crackles.
- Disable unnecessary processing
Temporarily turn off spatial audio, enhancement suites, noise suppression and heavy plugins.
- Match the media path
Use game/low-latency mode on earbuds or TVs and avoid routing audio through extra devices.
- Retest and record the result
Compare the new measurement with the baseline instead of judging from memory.
Cómo medir la latencia con precisión
Las pruebas del navegador son estimaciones prácticas. Mantén las mismas condiciones, repite varias veces y usa la mediana.
Use at least five attempts and ignore accidental taps or obvious outliers.
Do not switch codec, output device, browser tab or enhancement settings between runs.
Measure the TV, console, earbuds or interface exactly as you normally connect it.
Audio hardware latency and internet latency are different problems.

Preguntas frecuentes sobre latencia de audio
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.
