Frequently Asked Questions
What is AAC format?
AAC (Advanced Audio Coding) is a lossy audio compression format designed to be the successor to MP3. It typically provides better sound quality than MP3 at the same bitrate.
Is AAC better than MP3?
AAC generally provides better audio quality than MP3 at equivalent bitrates, especially at lower bitrates. However, MP3 has wider device compatibility.
What bitrate should I use?
192 kbps offers excellent quality for most uses. 256 kbps provides near-transparent quality and is standard for premium music services. 128 kbps is suitable for podcasts or when file size is critical.
Will converting from AIFF to AAC lose quality?
AIFF is lossless while AAC is lossy, so converting will result in some quality loss. However, at 192 kbps or higher, the quality loss is minimal and imperceptible to most listeners.
What devices support AAC?
AAC is widely supported on modern devices, especially Apple products, Android phones, and most media players. It's the standard format for iTunes and YouTube.
