輸入 1–5 首參考歌曲，分析曲風後生成近似風格的原創配樂。全部在瀏覽器內執行，音樂檔不會上傳到任何伺服器。Load 1–5 reference songs, analyse their style and generate original music in a similar style. Everything runs in your browser; your audio is never uploaded.

1輸入歌曲Input songs
支援 MP3 / WAV / M4A / OGG / FLAC，每首最長處理 10 分鐘。權重越高，該曲對風格的影響越大。讀入分析檔可直接略過第 2 步。MP3 / WAV / M4A / OGG / FLAC, up to 10 minutes per song. A higher weight gives that song more influence on the style. Loading an analysis file skips step 2.
2去除人聲（批次佇列）Vocal removal (batch queue)
逐首處理以節省記憶體：先以立體聲比對快速分離，伴奏用於分析和聲、律動與樂器，人聲用於擷取旋律特徵。AI 分離首次需下載約 67 MB 模型（之後快取），速度視電腦效能而定。選「不去人聲」時直接以原曲分析（適合純音樂或伴奏版），速度最快。分析完成後只保留特徵，完整音訊會釋放；伴奏與人聲另存一份低取樣率版本（約 22 kHz）供試聽，重新整理頁面後需重新放入歌曲才能試聽。Songs are processed one at a time to save memory: a fast stereo split first; the instrumental feeds harmony, groove and instrument analysis, the vocals feed melody features. AI separation downloads a ~67 MB model once (cached); speed depends on the computer. Choose No vocal removal to analyse the original mix directly (best for instrumentals; fastest). After analysis only the features are kept and the full-rate audio is released; a low-rate copy (~22 kHz) of the instrumental and vocals is kept for listening. After a page reload, add the songs again to listen.
3曲風分析與比較Style analysis & comparison
信心度低（紅 / 黃）時請確認：可能是半速 / 倍速、關係大小調混淆或拍號誤判。可直接修改 BPM、調性與拍號，修正後會重新計算並存入分析檔。Low confidence (red / yellow) means please check: half / double tempo, relative major / minor or a wrong meter are common. You can edit BPM, key and meter; corrections are recomputed and stored in the analysis file.
兩兩相似度Pairwise similarity
合併後的風格檔案Merged style profile
曲風標籤與樂器以頻譜特徵啟發式判斷，非經訓練的辨識模型。Genre tags and instruments are heuristic estimates from spectral features, not a trained classifier.
分析檔為 JSON 純文字（.aemlstyle.json），不含任何音訊；預設只存統計與原創性指紋，不含原曲旋律。開啟「保存完整旋律音符」後原曲旋律會寫入檔案，分享前請留意原曲著作權。The analysis file is plain JSON (.aemlstyle.json) without any audio; by default it holds statistics and originality fingerprints, not the original melodies. With "save the full melody notes" on, the original melodies are written into the file; mind the copyright of the originals before sharing it.

編制層次Arrangement
自訂格式：以 - 分隔段落，例如 Intro-A-A-B-A-Outro；可用 A:4 指定該段小節數。自訂結構時長度由結構決定。Custom format: sections separated by -, e.g. Intro-A-A-B-A-Outro; A:4 sets that section's bar count. With a custom structure the length follows the structure.
5生成與試聽Generate & preview
0:00 / 0:00
鎖定的聲部在「重新生成」時保持不變；鎖定旋律、和聲、貝斯或襯底音時和弦進行也會一併保留。Locked parts stay unchanged on "Regenerate"; locking the lead, harmony, bass or pad also keeps the chord progression.

生成記錄History
保留最近 12 次結果：可載入、設為 B 做 A/B 比較，或加入最愛（最愛不會被自動清除）。The last 12 results are kept: load one, set it as B for A/B comparison, or mark it as a favourite (favourites are never auto-removed).

全部在瀏覽器內編碼。開啟無縫循環時，循環點寫入 WAV 的 smpl 區塊或 OGG / FLAC 的 LOOPSTART 標籤，並另存一份循環點文字檔（_loop.txt）。檔案中繼資料會寫入作者與工具名稱。輸入歌曲的著作權屬原作者；本工具只學習風格，並以原創性檢查避免旋律雷同。Encoded entirely in your browser. With a seamless loop the loop points go into the WAV smpl chunk or the OGG / FLAC LOOPSTART tags, plus a loop-point text file (_loop.txt). Author and tool name are written into the file metadata. The input songs remain the property of their authors; the tool learns only the style and an originality check prevents melodic copies.

生成的曲子本身就是音符資料，樂譜與 MIDI 完全精確。MusicXML 為多聲部（含鼓譜），可用 MuseScore、Finale、Sibelius 開啟；多音軌 MIDI 的鼓組在第 10 聲道，可直接匯入 DAW 或遊戲引擎。The generated piece is note data, so score and MIDI are exact. MusicXML is multi-part (including a drum staff) and opens in MuseScore, Finale or Sibelius; the multi-track MIDI keeps drums on channel 10 for DAWs and game engines.
