QAudioEditor vs K

QAudioEditor is a lossless audio editor for iPhone and iPad. Open an MP3, AAC (.aac), M4A (.m4a), Apple Lossless, FLAC, or WAV file - or a video (MP4, MOV, M4V) to edit just its audio - see its waveform, and cut, crop, fade, normalize, copy/paste, or append audio - then save without re-encoding. Untouched audio is preserved byte-for-byte; only faded or normalized regions are adjusted, and always losslessly - MP3 and AAC by rewriting the codec's gain fields (the mp3gain/aacgain technique), and WAV, ALAC and FLAC in the sample domain - so there is no generation loss. SUPPORTED FORMATS - MP3 (MPEG-1/2 Layer III, constant or variable bitrate) - AAC - AAC-LC, HE-AAC and HE-AAC v2 - in ADTS (.aac) - AAC in MP4 (.m4a) - Apple Lossless / ALAC in M4A (.m4a) - FLAC (.flac), 16- and 24-bit - WAV / PCM (.wav), 8- to 32-bit and 32-bit float - Video (.mp4, .mov, .m4v) - the audio track is extracted losslessly for editing FEATURES - Frame-accurate cut, crop, and trim - Split markers - drop markers anywhere, drag them to fine-tune, and split a long recording into numbered files in one step (Pro) - Export Selection - save just the selected part as a new file - Very large recordings - multi-gigabyte WAV and FLAC files open, edit and save smoothly; the audio is kept on disk instead of in memory - Lossless fades and one-tap normalize - Pull the audio out of a video (MP4, MOV, M4V) - open it, or insert it at the playhead; AAC and ALAC tracks are extracted with no re-encoding - Cut, copy, paste, and insert or append other files of the same format (.aac and .m4a interchange freely) - Hardware-keyboard shortcuts on iPad - Playback follows the view - scroll to another part while playing and it plays from there - Rich waveform with peak + RMS view, zoom that stays centered on the playhead, and an overview navigator - Spectrogram view - see the frequency content over time on a log scale; toggle it with the waveform (cached for instant reopen) - File details, unlimited undo, and crash-safe session restore - Edit tags - title, artist, album and cover artwork - saved losslessly (MP3 and M4A/AAC) - Export raw AAC as a seekable .m4a - Record Stream (Pro) - record an internet audio stream (Icecast, SHOUTcast or HLS; MP3, AAC or FLAC) without re-encoding, until you stop it or for a set time, then edit the recording - it keeps recording with the screen locked, playing the stream while it records. Also available as a Shortcuts action - Universal purchase - buy once, use on iPhone, iPad and Mac Free to edit and to save results up to 5 minutes long. QAudioEditor Pro (a one-time purchase) removes the length limit so you can save recordings of any length, and adds Split at Markers and Record Stream - and one purchase unlocks Pro on iPhone, iPad and Mac.

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?
