MIDI에서 FLAC(으)로의 변환 소개

MIDI (.midi) files are the musical equivalent of source code — editable, lightweight, and infinitely flexible. A MIDI file of Beethoven's entire Fifth Symphony might occupy 60 KB, encoding every note, dynamic marking, and tempo change as discrete events. The .midi extension appears frequently in Linux distribution music packages (where Timidity++ or FluidSynth provides system-wide MIDI playback), in open-source game soundtracks, and in academic computational music research datasets.

FLAC (Free Lossless Audio Codec) is the universal open-source lossless audio standard, supported on every major platform including Windows, macOS, Linux, Android, and modern iOS. Converting MIDI to FLAC renders the symbolic music through software synthesis and preserves the complete audio output without any lossy compression, making it the ideal archival and audiophile format for MIDI renders.

MIDI을(를) FLAC(으)로 변환하는 이유

Open-source music projects — Linux distribution boot sounds, game soundtracks for FOSS games, creative commons music libraries — frequently start as MIDI compositions. When these projects need to ship audio rather than MIDI, FLAC is the natural choice: patent-free, lossless, and universally supported. It aligns with the open-source philosophy that typically surrounds .midi-based workflows.

Audiophile listeners who want to hear MIDI compositions at their absolute best should render to FLAC. Unlike lossy codecs that discard inaudible frequencies (psychoacoustic masking), FLAC preserves the complete spectrum of the synthesis output. When combined with a high-quality SoundFont, FLAC MIDI renders can be genuinely impressive — indistinguishable from the direct synthesis output.

작동 방식

FFmpeg processes the .midi file through its SMF decoder, constructing a timeline of MIDI events with absolute timestamps derived from the tempo map and PPQN division. The synthesis engine processes these events through a SoundFont bank: program changes select instrument patches, note-on events trigger sample playback with velocity-sensitive parameters (filter cutoff, amplitude, sample offset), and continuous controllers modulate the sound in real time. The resulting PCM audio is compressed by FLAC's encoder pipeline: decorrelation (mid-side for stereo), linear prediction (up to 32nd order), residual encoding, and Rice/Golomb entropy coding — all completely reversible upon decoding.

품질 및 성능

FLAC is mathematically lossless — the decoder produces PCM identical to the encoder input. Synthesized MIDI audio typically achieves 40-50% FLAC compression ratios, slightly better than live recordings because synthesis output has lower noise floors and more structured waveform patterns. The quality perceived by the listener depends entirely on the SoundFont. For audiophile-oriented renders, use SoundFonts built from high-resolution (96 kHz/24-bit) instrument recordings with natural room ambience and articulation switching for the most convincing results.

최상의 결과를 위한 팁

1Use FLAC compression level 5 for the best speed-to-size balance — levels above 8 provide diminishing returns
2Tag the FLAC output with Vorbis comments (TITLE, ARTIST, ALBUM, TRACKNUMBER) for organized library management
3Render at 44.1 kHz 16-bit for distribution or 48 kHz 24-bit for production masters
4Store the original .midi file alongside the FLAC render — MIDI can be re-rendered as SoundFont technology improves
5For open-source projects, document the SoundFont used in the FLAC metadata so renders can be reproduced exactly

자주 묻는 질문

No. FLAC compression levels (0-12) only trade encoding time for file size. Level 8 produces slightly smaller files than level 5 but takes longer to encode. The decoded audio is bit-identical at all levels.

Synthesized audio has a cleaner noise floor and more predictable waveform patterns than microphone recordings. FLAC's linear prediction model fits this structured signal more efficiently, yielding better compression ratios.

iOS has supported FLAC playback since iOS 11. The Files app and Apple Music app both play FLAC natively. No third-party app is required on modern iOS devices.

Both are mathematically lossless. FLAC has broader cross-platform support and slightly better compression. ALAC integrates more tightly with Apple Music and iTunes. For non-Apple-specific archival, FLAC is the standard choice.

Yes. FLAC supports Vorbis comment tags where you can store title, artist, album, and custom fields. MIDI track names and text events can be manually transferred as Vorbis comments during or after conversion.
