The pitch preservation keeps everything in the correct key while you practice. For Dancers: Isolate the 8-count you're struggling with, loop it endlessly at slower speed, and perfect your moves before moving on. Use bookmarks to save different sections of the choreography. For Language Learners: Replay that native speaker's pronunciation 50 times at 0.8x speed until you've got it down perfectly. The tempo control makes it easier to catch every sound. For Students: Loop the critical part of a lecture, adjust the EQ to clarify the speaker's voice, bookmark it with notes, and return to it during exam prep. 🎓 FEATURES IN DETAIL Loop Control: The A/B looping system uses Web Audio API crossfading to eliminate the clicks and gaps you hear with basic video looping. The 30ms crossfade creates truly seamless playback, just like professional hardware loopers. Tempo Without Pitch Change: Unlike YouTube's native speed controls, YT Loop Station preserves the original pitch when you change tempo. This means you can slow down music to 0.5x for detailed practice without everything sounding low and muddy. Professional EQ: The 5-band equalizer gives you surgical control over the frequency spectrum. Boost the bass to hear that kick drum pattern, cut the mids to isolate the guitar, or enhance the highs for clearer vocals. Each band ranges from -12dB to +12dB. Pitch Shifting: Change the key of any video without affecting the tempo. Perfect for matching a song to your vocal range or practicing in different keys. Uses equal temperament tuning (semitone = 2^(1/12)) for musical accuracy. Jog Controls: Fine-tune your loop points with ±50ms precision using the jog buttons. This is essential for catching the exact start of a musical phrase or the precise moment a dance move begins. Bookmarks: Save unlimited loop configurations with custom names. Each bookmark stores the A/B points, tempo, volume, pitch, and EQ settings. Great for practicing multiple sections or coming back to specific parts later.
