Ready to develop "golden ears" like a pro audio engineer? Whether you're a music producer, audio enthusiast, or a student dedicated to improving your listening skills, EarMaster is your personal, pocket-sized ear training coach. We skip the dry theory and get straight to what matters. Through a series of carefully designed interactive training and evaluation modules, you'll master the two most critical skills in audio production: Frequency Recognition and Dynamics Processing. 【KEY FEATURES】 **Frequency Training** * Build your intuition for the audio spectrum, from the 6 fundamental bands to hundreds of advanced frequency points. * Learn to identify and distinguish the "punch" of sub-bass, the "core" of vocals in the mids, and the "air" of the high frequencies. **Dynamics Training** * Deep dive into the four essential parameters of a professional compressor: Threshold, Ratio, Attack, and Release. * Through comparative listening, learn how different settings can shape the punch, breath, and tightness of any sound. **NEW! Explore Mode** * Your personal sound laboratory! Tweak all compressor parameters in real-time within a professional-grade interface. * Visualize the changes with a live transfer curve graph and an accurate gain reduction meter. * Experiment freely on looping audio sources to perfectly connect theory with practice. **Evaluation & Records** * Test your skills with ABX-style quizzes and challenge your listening acuity. * Receive detailed reports with accuracy, response time analysis, and your most common mistakes to pinpoint areas for improvement. * Track all your training and evaluation sessions to see your progress over time. 【WHO IS IT FOR?】 * Music Producers & Mixing Engineers * Podcasters & Video Editors * Audiophiles & Hi-Fi Enthusiasts * Music & Audio Technology Students * Anyone who wants to sharpen their critical listening skills. Download EarMaster now and start your professional ear training journey. Turn your ears into your most powerful tool!

【アプリの紹介】 「SpectrumAnalyzer」は、デバイスのマイクから取得した音声をリアルタイムで高度に解析・可視化するオーディオDSPビジュアライザです。 高速フーリエ変換(FFT)を用いた精密な周波数解析と、直感的で洗練されたダークテーマのユーザーインターフェースにより、音響エンジニアから音楽家、音に興味のある一般のユーザーまで、どなたでも手軽に「音の形」を観察することができます。 【主な機能】 リアルタイム表示 - 時間領域(波形): 音の強弱を波の形でリアルタイムに描写します。 - 周波数領域(スペクトラム): 音にどの周波数がどれだけ含まれているかを解析します。 - 同時表示: 波形とスペクトラムを上下に並べ、音の挙動を立体的に捉えます。 プロレベルのDSP設定パラメータ - FFTサイズ選択: 512, 1024, 2048, 4096サンプルから解像度を選択可能。 - 豊富な窓関数(Window): None(矩形窓), Hann(ハニング窓), Hamming(ハミング窓), Blackman(ブラックマン窓)をサポート。 - 周波数重み付け特性(Weighting): フラットな「Z特性」、人間の聴覚特性に合わせた「A特性」、騒音評価に用いられる「C特性」をワンタップで切り替え。 リファレンス・重ね合わせ(オーバーレイ)機能 - マイクからの音声を一時録音し、全体の「平均スペクトル」を瞬時に算出。 - 保存した平均スペクトルを、リアルタイムの解析波形の上に重ね合わせて表示することで、異なる音源の周波数特性を簡単に比較できます。 - 音声の録音と再生 - 録音した音声はその場で再生して確認が可能です。 【こんな用途におすすめ】 オーディオ機器やスピーカーのチューニング:部屋の音響特性や周波数バランスの測定に。 楽器の練習やチューニング:倍音構成の視覚的な確認やピッチチェックに。 ボイストレーニング・発声練習:自分の声の周波数成分の分析に。 環境音や騒音の調査:周囲の雑音がどの周波数帯域で発生しているかの特定に。

Verdict
The clearest difference is update cadence: SpectrumAnalyzer at daily against EarMaster's every 2 days. EarMaster's advantage is iOS requirement (17 vs 26.5). On price, ads, in-app purchases and device support there is nothing between them.
