¿Qué son Archivos de Audio? Definición y lista de extensiones
Los archivos de audio almacenan datos en forma de onda que se pueden escuchar con un software de reproducción de audio. Los archivos de audio incluyen formatos de audio comprimido (para su almacenamiento o transmisión más rápida) o archivos sin comprimir que contienen datos en forma de onda que se puede tocar con el software de reproducción de audio. Archivos de audio también incluye los archivos MIDI, partituras musicales, y otros proyectos de audio.
Los archivos de archivo de audio sin compresión son conocidos como PCM, normalmente se almacena como .wav para Windows o como .aiff para MAC. WAV y AIFF son formatos de archivo flexibles diseñados para almacenar más o menos cualquier combinación de frecuencias de muestreo. Esto los convierte en formatos de archivo adecuados para el almacenamiento de la grabación original.
Los archivos de audio comprimidos con pérdida son utilizados en los ordenadores actuales y otros equipos multimedia. El más conocido de los formatos de audio comprimidos es MP3 (MPEG-1 Audio Layer 3). Formato de archivo MP3, es un formato de audio digital patentado de codificación utilizando una forma de compresión de datos con pérdidas. Es un formato de audio común para el almacenamiento de audio, así como un estándar de compresión de audio digital para transferencia de música en reproductores de audio digitales.
Un formato comprimido sin pérdidas requeriría un mayor procesamiento por el mismo tiempo de procesamiento. FLAC (Free Lossless Audio Codec) es un formato comprimido sin perdida, lo que significa que la información de audio se comprime en el archivo FLAC sin ninguna pérdida en la calidad de audio. Esto es similar a cómo funciona Zip, excepto que con FLAC conseguirás mejor tasa de compresión ya que está diseñado específicamente para archivos de audio.
Las extensiones de archivos de audio permiten al sistema operativo identificar a los archivos que contienen sonido, voz o música embebida. Las extensiones de archivos de audio más utilizadas son: .wav, .aif, .mp3, y .mid.
