リハーサル録音の「聞き返し」に革命を。 合奏練習を録音しても、数時間のデータから特定の指示箇所や演奏箇所を探すのは大変な作業ではありませんか? RehearsalLink(リハーサルリンク)は、音楽家・指導者のために開発された、録音ファイルをAI解析して「目次」を付けるインデクサーです。 【主な機能】 自動セグメンテーション: 音声解析により、録音を「演奏」「会話」「無音」に自動分割。波形が色分けされるので、視覚的に内容を把握できます。 指示内容をテキスト化: 指導者の言葉を最新の音声認識エンジンで文字起こし。録音をすべて聞き返さなくても、何を話していたか一目で分かります。 AIによる練習要約: 文字起こしデータから、練習の要点を自動抽出(OpenAI / Anthropic / Gemini 連携)。次の練習への課題が明確になります。 スマートな書き出し: 「演奏箇所だけ」あるいは「会話だけ」を結合してエクスポート。移動中の確認用ファイルの作成も一瞬です。 マルチデバイス対応: iPhone/iPad で手軽に録音・確認。Mac 版(別売/同梱)で詳細な編集や要約。iCloud またはファイル共有でシームレスに連携。 【こんな方におすすめ】 合奏の録音を効率的に振り返りたい吹奏楽・オーケストラ・バンドの皆様 自分の指導内容を客観的に確認したい指導者の方 練習の「要約」をメンバーに共有したいコンミス・パートリーダーの方 プライバシーを重視し、音声認識はデバイス上(オンデバイス)で完結。AI要約機能のみ、ユーザー自身のAPIキーを使用して安全にクラウド連携します。

Read full description

HarmoTuner is a tuner and metronome designed to help ensembles explore harmony through just intonation. Alongside precise single-note tuning, HarmoTuner lets you choose a target chord and compare the current position of each chord tone with its just-intonation target. Use it for individual long-tone practice or for shaping intonation and resonance in wind bands, orchestras, chamber groups, and other ensembles. CHORD TUNING Choose a target from 96 chords, including C, Am, G7, and CM7. HarmoTuner detects up to four input tones and displays a separate gauge for each role in the chord, such as the root, third, fifth, and seventh. In addition to the deviation from equal temperament, a target marker shows where each tone sits in just intonation. You can also find possible chords by selecting the note names you hear, making it easy to choose a target even when you do not know the chord symbol. SINGLE-NOTE TUNER View the note name, frequency, and deviation in cents from the selected reference in real time. • Adjustable A4 reference pitch • Equal temperament, just intonation, Pythagorean tuning, and meantone temperament • Adjustable input sensitivity and lock sensitivity • Lock indicator for a stable pitch • Reference tone with selectable note and octave • Analysis display for waveform and harmonic content Use it not only for tuning an instrument, but also for long tones and for checking the stability of embouchure and breath support. METRONOME Set the tempo, meter, and subdivision, then follow the beat through sound and visual feedback. • 30–300 BPM • Meters from 1/4 to 10/4 • Quarter-note, eighth-note, triplet, and sixteenth-note subdivisions • Tap tempo • Tempo marking display • Optional screen-edge beat flash Practice intonation and tempo without switching between apps. THREE FOCUSED MODES Open Tuner, Chord, or Metronome directly from its own tab. HarmoTuner remembers your most recently used mode and settings, so you can get back to practice quickly. PRIVACY All microphone input is analyzed on your device. HarmoTuner does not save recordings, transmit audio to external servers, or collect personal information.
