SingSpark 2.9 turns practice into a more complete private vocal studio, from building a Voice Profile and breaking down song phrases to reviewing exactly what needs work after each take. ・Added a 3-day full-feature trial for recording, training, song analysis, phrase looping, polish, and export ・Added Voice Profile for range, stability, and key-fit suggestions that can guide song analysis ・Added Singing Training Adventure with daily drills for pitch, scales, intervals, timing, high notes, and vocal technique ・Improved song phrase analysis so imported lines can show reference pitch, beat points, hard phrases, and recommended drills ・Added vocal separation and caching so song analysis can focus on the vocal guide and reload processed audio faster ・Improved post-recording coach scores with reference-pitch comparison, accuracy, coverage, average pitch offset, and timing offset ・Improved weak-phrase review so you can loop the sections that need the most repair directly from the score ・Improved polish and sharing with pitch correction, clarity, reverb, loudness cleanup, and export

SingSpark 2.7 makes song analysis feel more like a real vocal coach: it checks whether the reference pitch is reliable before judging pitch, timing, and practice sections. ・Added reference-pitch reliability, combining confidence, level, vocal activity, and continuity so unclear moments are not judged too aggressively ・Improved song sectioning, moving from fixed cuts to more natural practice phrases based on pauses, vocal landings, pitch turns, and beat cues ・Improved timing analysis with local high-resolution re-analysis around note entries and pitch landings ・Improved pitch cleanup to reduce false detections from backing instruments, soft attacks, and short pitch jumps ・Improved technique scoring so sections without enough evidence are no longer given a forced technique score ・Improved score explanations to show whether a result came from pitch center, stability, timing, or an unclear reference line ・Improved mistake-section practice with phrase-like sections that are less likely to be too short or musically unnatural ・Improved analysis caching so older results are refreshed for the new analysis logic, then load faster next time

SingSpark 2.6 makes the full practice flow smoother, from backing tracks and vocal guides to recording and playback analysis. ・Added optional vocal removal when importing backing tracks, while keeping the extracted vocal pitch as a sing-along guide ・Added separation caching so processed songs can be loaded again without starting from scratch ・Added original-vocal blend controls so you can balance the song, vocal guide, and your own voice while practicing ・Improved recording playback with separate voice/backing track controls for volume and timing offset ・Improved the pitch view with clearer naming, time axis, and pitch axis ・Improved post-recording scoring so pitch, timing, and mistake sections are easier to review and practice again ・Improved microphone selection with a cleaner recording UI and safer input handling after recording starts ・Improved performance across song analysis, vocal separation, live pitch charts, and animated backgrounds

SingSpark 2.5 makes the vocal coach steadier, smarter, and closer to how people hear singing: ・Improved pitch analysis so runs, slides, scoops, and vibrato are judged by their musical center instead of treated as simple instability ・Improved register detection for chest, mix, head voice, and falsetto, with less jumping at note onset ・Improved karaoke practice with clearer target pitch, live voice, and offset feedback ・Improved song analysis with cleaner vocal pitch curves and less backing-instrument interference ・Improved microphone switching between phone and headset mics to avoid audio format crashes ・Improved recording with backing tracks, including clearer voice/backing level and latency adjustment flow ・Improved training feedback: target tones keep playing and post-note feedback stays visible longer ・Improved performance and stability during song analysis, live pitch tracking, and UI updates

SingSpark 2.0 is a major vocal coach update: ・New Song Analysis: import a phrase and break down reference pitch, beat points, and practice segments ・New karaoke pitch practice: play the original song while viewing the target pitch and your live voice ・Upgraded vocal separation with an MDX Core ML pipeline to reduce backing instruments in pitch analysis ・New Vocal Training Adventure with pitch, scale, interval, timing, and high-note drills ・New Voice Profile for faster range, stability, and key-fit guidance ・New coach-style polish for pitch tuning, reverb, loudness, and export sharing ・Improved analysis cache, progress feedback, UI performance, and memory use during song analysis ・Improved onboarding, bottom navigation, and practice screens for a clearer first-time experience
