Preguntas Frecuentes

Cambiar el tempo afecta la calidad del audio?

Nuestro algoritmo Rubberband mantiene alta calidad incluso en cambios de tempo extremos. Sin embargo, velocidades muy lentas (por debajo de 0.5x) pueden introducir algunos artefactos dependiendo del contenido de audio.

Cual es la diferencia entre tempo y velocidad?

El tempo cambia solo la velocidad mientras preserva el tono. La velocidad cambia tanto el tempo como el tono juntos. Usa tempo para practica sin cambiar la tonalidad.

Puedo cambiar el tempo de archivos muy largos?

Los archivos se procesan en tu navegador, por lo que archivos muy largos pueden estar limitados por la memoria de tu dispositivo. La mayoria de canciones menores a 10 minutos funcionan bien.

Por que tarda tiempo en procesar?

Rubberband es un algoritmo sofisticado que analiza el audio para mantener la calidad. El tiempo de procesamiento depende de la longitud del archivo y la potencia de procesamiento de tu dispositivo.
