MP3Gain vs QAudioEditor

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. Import from anywhere • Select files from the Files app • Pull tracks straight from your Music Library • Open an audio file in MP3Gain from any app Note: DRM-protected tracks — for example, Apple Music subscription titles — can't be imported or processed.

QAudioEditor is a lossless audio editor for iPhone (including iPhone Duo) 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, 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 name them; split a long recording into files in one step, each named and tagged after its marker (Pro) - Markers at Silences - finds the pauses between the tracks of a recording, such as an album saved as one file, and drops a marker in each, ready to split (Pro) - Chapters (Pro) - save markers as chapters in MP3 and M4A/M4B, for podcasts and audiobooks; chapters in a file you open become named markers - ReplayGain tags - measure the loudness and tag the file so players level the volume, with no change to the audio (MP3, M4A, FLAC) - CUE sheets - import a .cue file as markers, or export your markers as .cue - Loudness - LUFS, peak and loudness range in File Details - Trim Silence (Pro) - cut the silence at the start and end in one step - 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 - 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 - File details, unlimited undo, and crash-safe session restore - Edit tags - title, artist, album and cover artwork - saved losslessly (MP3, M4A/AAC, FLAC) - 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, with a marker named after each song - it keeps recording with the screen locked - Shortcuts actions - Normalize, Write ReplayGain Tags, Trim Silence, Split at Silences and Record Stream Free to edit and to save results up to 5 minutes long.
