Convert MP4 to AAC

AAC is essentially the next generation after MP3 - it produces better sound quality at the same file size. When you extract audio from videos, AAC preserves more detail, offers clearer highs, and handles complex sounds like orchestral music better than MP3. It's especially noticeable at lower bitrates - a 128kbps AAC file often sounds as good as a 192kbps MP3. Plus, AAC supports more advanced features like multichannel audio and better handling of stereo positioning.

Yes, AAC has excellent compatibility across modern devices. It works natively on all Apple products (iPhone, iPad, Mac), Android devices, smart speakers, most modern TVs, and practically all software media players. It's actually the standard format for YouTube, iTunes, and many streaming services specifically because of this broad compatibility. Unless you're dealing with very old equipment, AAC files will play without issues on virtually any device you use.

For most content, 128kbps provides an excellent balance of quality and file size - this is actually what many streaming services use. If you're extracting high-quality music and have space to spare, 192kbps or 256kbps gives you near-transparent quality that's virtually indistinguishable from uncompressed audio for most listeners. For voice-dominant content like lectures or interviews, you can go as low as 96kbps or even 64kbps and still maintain good clarity while creating very small files.

AAC excels at both! It was designed to efficiently handle a wide range of audio content. For music, it preserves stereo imaging and frequency response better than older formats. For speech, AAC's advanced psychoacoustic modeling ensures voices remain clear and natural even at lower bitrates. This versatility makes it perfect when you're extracting mixed content from videos - whether it's music videos, vlogs with background music, podcasts, or interviews, AAC adapts well to different audio types.

While professional audio production typically uses uncompressed formats (like WAV or AIFF) for working files, AAC is widely accepted as a high-quality delivery format. Many professionals use AAC for client previews, portfolio samples, or final distribution when uncompressed formats aren't practical. At high bitrates (256kbps or higher), AAC quality is excellent enough for most professional applications where the priority is distributing finished content rather than further editing.
