О конвертации MPEG в AAC

MPEG video files carry both video and audio tracks, with the audio typically encoded as MPEG Audio Layer 2 (MP2) at 192-384 kbps. AAC (Advanced Audio Coding) is the successor to MP3, standardized in MPEG-2 Part 7 and refined in MPEG-4 Part 3, delivering better sound quality at equivalent bitrates. Extracting audio from MPEG to AAC preserves more fidelity per kilobyte than converting to MP3.

Зачем конвертировать MPEG в AAC?

MPEG Audio Layer 2 is a capable codec, but it lacks the psychoacoustic refinements of AAC. At 128 kbps, AAC achieves audio quality comparable to MP2 at 192 kbps, making it significantly more storage-efficient. AAC is also the native audio format for Apple devices, iTunes, YouTube, and most streaming platforms.

Extracting audio from MPEG recordings — such as TV captures, VHS digitizations, or DVD rips — into AAC gives you compact, high-quality audio files ready for modern playback ecosystems. Whether you need podcast-ready speech from a broadcast recording or a clean music track from a concert tape, AAC provides the best lossy quality available.

Как это работает

FFmpeg strips the video stream entirely and re-encodes the MP2 audio to AAC using the native FFmpeg AAC encoder or libfdk_aac (higher quality). Typical parameters: `-vn -acodec aac -b:a 192k -ar 44100`. The VBR mode (`-q:a 2`) is recommended for variable-bitrate encoding that allocates more bits to complex passages and fewer to silence.

Since both MP2 and AAC are lossy codecs, there is a generational quality loss. However, if the source MP2 was encoded at 256 kbps or higher, transcoding to AAC at 192 kbps VBR will produce output that is perceptually transparent to most listeners. For archival purposes, consider extracting to FLAC first, then re-encoding to AAC.

Советы для наилучших результатов

1Use VBR mode (-q:a 2 in FFmpeg) for optimal quality-to-size ratio — it adapts bitrate to audio complexity
2Normalize audio levels after extraction if the source MPEG had inconsistent volume (common in TV recordings)
3Check if the MPEG audio is already MP3 — if so, you can extract it losslessly with `-acodec copy` to MP3 instead
4For speech-only content like lectures, 96 kbps AAC-HE provides excellent intelligibility at tiny file sizes
5Add metadata tags (title, artist, album) during conversion to keep your audio library organized

Часто задаваемые вопросы

Yes, because both MP2 (the typical MPEG audio) and AAC are lossy. You are transcoding from one lossy format to another. However, at adequate bitrates (192+ kbps AAC), the loss is minimal and rarely perceptible.

128 kbps is fine for speech content. For music, use 192-256 kbps. If storage is not a concern, 320 kbps AAC is effectively transparent quality for all content types.

Only if the MPEG already contains AAC audio, which is uncommon — most MPEG-1/2 files use MP2 or MP3 audio. If the audio is already AAC, FFmpeg can copy it directly with `-acodec copy`.

Yes. AAC playback has been supported on Android since version 1.0. It is also the default audio format for YouTube, Spotify, and Apple Music.

Dramatically smaller — you are discarding the entire video stream. A 1GB MPEG file might produce a 30-50MB AAC file, depending on audio duration and bitrate.

AAC produces better quality at the same bitrate, especially below 128 kbps. MP3 has slightly broader compatibility with very old devices. For modern use, AAC is the better choice.
