Formatos de Áudio Explicados: MP3, FLAC, AAC, OGG, WAV — Qual Usar
Uma comparação clara de formatos de áudio populares — qualidade, tamanho do arquivo, compatibilidade e quando usá-los.
Choosing the right audio format depends on your use case: archival quality, streaming efficiency, device compatibility, or file size constraints. Each format makes different tradeoffs.
MP3 remains the universal choice — supported by every device and platform. At 320 kbps, MP3 quality is indistinguishable from CD for most listeners. At 128 kbps, it is excellent for podcasts and spoken word. File sizes are moderate.
FLAC is the gold standard for lossless audio. It compresses CD-quality audio by 50-70% without losing any data. Every bit is preserved, making FLAC ideal for archival, audiophile listening, and professional mixing. The downside: files are 3-5x larger than high-quality MP3.
AAC (Advanced Audio Coding) is MP3's successor, delivering better quality at the same bitrate. It is the default format for Apple devices, YouTube, and most streaming services. AAC at 256 kbps matches MP3 at 320 kbps in most blind tests.
OGG Vorbis is an open-source alternative to MP3 and AAC with excellent quality and no licensing restrictions. WAV is raw, uncompressed audio — perfect for editing but impractical for distribution due to enormous file sizes. ConvertCraft converts between all these formats in your browser.
