MP3Gain vs K

Make all your audio the same volume — without touching the volume dial. Ever jump from one song to the next and grab for the volume button? Or finish a podcast that's twice as loud as the one before? MP3Gain fixes that. It measures the true loudness of your audio and applies exactly the right amount of gain, so everything you listen to, share, or upload sounds even and professional. Quick for everyday fixes. Precise for creators. Three measurement modes cover every job: • Peak — match tracks to a target peak level (in dB). • RMS — match the average energy of your tracks for consistent perceived volume. • EBU R128 (LUFS) — the international loudness standard used by streaming and broadcast platforms, with true-peak limiting. Built-in presets Start in one tap with presets tuned to real-world targets, and save your own for repeat jobs. • Music — RMS -20 dB • Podcast — EBU R128 -16 LUFS • Voice — EBU R128 -18 LUFS • Streaming Video — EBU R128 -14 LUFS • Default — EBU R128 -23 LUFS Batch processing Import a whole album, playlist, or batch of files and normalize them all at once. Adjust one file and apply the same settings to every file in your list. Progress is shown per file, and you can cancel anytime. Hear it before you export Play the original and the processed version side by side in the app, so you know it sounds right before you save or share it. Keep your music intact MP3Gain preserves embedded album art and metadata. Lossy formats keep their original bitrate; lossless files are processed without additional lossy compression.

K-Tuner is a guitar tuner you can use without looking at the screen. Pluck a string and it hears which string you played. Once the note settles, it tells you in words: "String 6, in tune", "too low", or "too high". Turn the peg, pluck again, and listen. It is designed to work with VoiceOver from the ground up. Nothing important is shown only by color or by the position of a needle. Every result is spoken. HOW IT WORKS • Open the app and it starts listening right away. • Pluck one string. K-Tuner picks the string automatically. You can also tap a string button to lock it. • When the note settles, it speaks the result. It stays quiet while you are turning the peg, so it never talks over you. • If the note fades too soon, it gives you a rough reading such as "probably too high" instead of staying silent. • If another string is ringing and hiding the one you plucked, it tells you which string to mute. • Tap "Speak current reading" at any time to hear the string and how many cents it is off. MADE FOR VOICEOVER • Every control has a clear label and hint. • Start or stop with a two-finger double-tap (magic tap), so you never have to find a button while holding your guitar. • The meter and the constantly changing numbers are hidden from VoiceOver so the focus never jumps around. • Results are announced in the language of the app, and the announcements do not interrupt each other in the wrong order. NOT USING VOICEOVER? Turn on "Speak aloud" in Settings and K-Tuner speaks the results itself, at the rate you choose. Sighted players get a large circular meter with a needle that turns green when the string is in tune. CAPO Tuning with a capo on? Set the capo fret right on the tuner screen and every string's target moves up with it. FREE VERSION • Standard tuning (E A D G B E) • Capo • Automatic string picking • Spoken results and VoiceOver support • The visual meter K-TUNER PRO (one-time purchase) • 18 more tunings: half step down, whole step down, Drop D, Drop C, Drop B, Open D, Open E, Open G, Open A, Open C, DADGAD, Nashville, all fourths, all fifths, major thirds, guitalele, and ukulele (high G and low G) • Reference pitch from 430 to 445 Hz Pro is a single purchase, not a subscription. Buy it once and use it on all your iPhones and iPads with the same Apple ID. PRIVACY K-Tuner uses the microphone only to measure pitch. Nothing is recorded or saved, and no audio ever leaves your device. There are no accounts and no ads. If something goes wrong, you can choose to email the developer an activity log; it contains no audio. TIPS • Place your iPhone near the body of the guitar with the microphone facing it. Your lap or a music stand works fine. • Pluck with normal strength. A very hard pluck takes longer to settle. • Keep the microphone out of air-conditioner drafts. Questions or feedback?
