What’s New
Practical updates for musicians, practice rooms and audio testing.
The Adjust & Save Audio workspace now creates 24-bit WAV, 16-bit WAV, lossless FLAC, MP3 320 kbps, or MP3 192 kbps. The original audio stays on the user's device throughout processing and file creation.
The Adjust & Save WAV workspace now includes an optional L/R CENTER CORRECTION setting. It measures the average balance across the full stereo file and redistributes the left and right levels without reducing their combined energy before creating the new WAV.
Desktop users can now choose standard playback goals, a loud master at -10 LUFS, or an extreme master at -7 LUFS. The PRESERVE, BALANCED, and GOAL PRIORITY approaches provide clearly different amounts of level control.
Download Windows VST3, macOS VST3, or Logic AU Beta 0.5. The Mac builds support Apple Silicon and Intel Macs and are signed with a Developer ID certificate and notarized by Apple.
Virtual Headphones added a dedicated plug-in path and improved browser comparison flow. Favorites, recent models, Quick Compare, notes, and last-used settings make target checks faster.
Acoustic Planner moved from public beta to stable. This update period also added reverberation estimates, level and decay result views, furniture-aware first reflections, Virtual Listening refinements, and desktop project-file opening.
Choose the headphones you own, load a familiar audio file, and compare the measured tonal balance of 2,898 headphones and earphones. The audio file stays in your browser.
Build a room or venue in 2D and 3D. Add materials, furniture, acoustic treatment, speakers, and listening positions, then review practical acoustic estimates before changing the real space.
The Home page now introduces the site through system checks, ear training, and audio analysis. Three signature tools appear before the full directory, while the full directory remains easy to open.
Visitors can now leave a public comment without creating an account. Written comments from tool Feedback can also appear here, and SolAudioLab can reply directly below each comment.
Audio Analyzer now explains that the score shows the technical condition of the audio file, not the artistic quality of the song. The waveform view also includes a small peak overlay toggle so dense peak markers can be hidden when they cover the waveform.
Feedback Trainer now includes Free Practice, automatic next-round advance, and refined cut judgment. Listen Mode remains available for hearing each frequency band before training.
Audio Analyzer now gives clearer Friendly Suggestions for files that need remastering decisions. It can suggest when to avoid more compression, when to repair peak problems first, and when to check stereo balance before final limiting.
Audio Analyzer now separates integrated loudness, sample peak, estimated true peak, and peak-event patterns. It treats isolated lossy-codec peak overs differently from likely hard clipping.
Tone Generator now keeps precise frequency control close to the main controls. Saved frequencies and an auto stop timer were added below the main panel, while longer usage guidance stays in the lower page section.
The main tool area now uses compact list rows. The separate Quick Finder panel was removed. New tool badges now use a warmer orange accent.
Speaker System Check is a guided page for checking a speaker setup. It checks stereo channels and the mono center image. It also checks speaker matching, polarity, and low-frequency rattle or buzz with controlled browser-generated test signals.
Each tool now includes a quick feedback panel. Users can rate the tool, check useful points, choose improvement areas, and leave an optional short comment. This helps collect real issues by tool.
Room Clap Test uses two comfortable hand claps to show room decay. It also compares frequency-band decay, checks repeating reflections, and reviews measurement quality without external test speakers.
A shared browser translation guide is now available in five languages across all tools. Tool names, audio terms, units, and the SolAudioLab brand remain in English.
Tuner uses harmonic candidate scoring and temporal tracking. This reduces octave jumps, follows peg movement more smoothly, and rejects irregular background noise.
The compact player keeps the listening guide, controls, A–B loop, and current list in view. Tracks can be played with one click, and Quick Compare can jump to saved timecodes.
Compact tool rows make the full directory easier to scan. The directory covers audio tools, live-sound tools, and practice tools.
Full-range pink noise now fades in safely before feedback rises. The page also uses hardware-style GEQ faders, a clear 0 dB center position, and realistic black slots.
The beat display now uses wider fixed spacing. Downbeats and regular beats use paired colors. A 12-beat pattern appears as two rows of six beats, and the BPM display is balanced.
Practice finding feedback frequencies. Then choose cuts with a GEQ-style trainer and keep a local Last Session reference.
The metronome click is now louder and clearer. Standard, Cutting, and Soft tone choices help with practice, drum monitoring, and in-ear monitoring.
Use the left and right arrow keys to sweep frequencies steadily. Normal and Fast speed options help with speaker and room checks.
Pattern Setup now uses a simple Grid choice instead of manual Steps. Time changes automatically reshape the pattern grid and beat labels.
Bar 1-8 navigation and Copy, Paste, Duplicate, and Clear actions now stay on the mobile editor. You no longer need to open the BARS panel to change bars.
A lightweight signal activity display for the left and right channels was added below the main control panel. You can check speaker output visually while testing.
Count-in now uses a dedicated short beep. The final count-in adds an octave-up tone, so the start cue is easier to recognize before the real beat begins.
The Stereo Balance meter direction was corrected. Left and Right now match the analysis text and waveform reading.
A new Master Volume slider was added near Tap Tempo. Rhythm practice volume can now be adjusted without opening advanced mix settings.
Rock 8 Beat, Funk Groove, and Reggae One Drop presets were added. Practice patterns can now start faster.
The homepage now shows a Popular Tools graph based on tool page openings. This helps visitors find active tools faster.
The mobile page now keeps BPM, Start/Stop, and Tap Tempo easy to reach. A compact mobile control bar makes stopping safer.
The mobile page now prioritizes Play, BPM, and the pattern grid. Quick presets are placed up front, and advanced settings are in expandable sections.
The mobile page now prioritizes frequency, play/stop, volume, waveform, and quick presets. Harmonic Mix and Sweep are in expandable advanced sections.
The mobile page now prioritizes file selection, analysis status, and Quick Summary results. Graphs and details are in expandable sections.
Choose your own local audio file and play it directly in the browser. No upload required.
Extra playback and output boxes were removed. LEFT, BOTH, RIGHT, volume, and mute now stay simple.
Capo chord cards now use a compact mobile layout. This makes it easier to copy chords to a score.
Recommendations now consider real-world playability, barre chords and high capo positions.
Each capo position from Capo 1 to Capo 11 now includes a visual preview.
Enter a song key to find practical capo positions. Then see the chord shapes you can play.
Pattern editing, transport controls, and the mobile layout were refined. Practice setup is now faster on small screens.
Speaker Test was the first tool on the site. It launched with LEFT, BOTH, and RIGHT speaker testing.
