AudioConverter 27.9.3
converts audio quickly and accurately between MP3, AAC, ALAC, FLAC, WAV, OGG, OPUS and VORBIS: batch processing, metadata and artwork, EBU R128 loudness normalization, and spectral analysis of your files.
converts audio quickly and accurately between the popular formats: MP3, AAC, ALAC, FLAC, WAV, OGG, OPUS and VORBIS. Batch processing, metadata and artwork transfer, flexible quality settings — and a workflow that makes sense for everyday work with a music library.
And it does more than shuffle bytes around. It shows you what is really inside a file, brings loudness in line with the broadcast standard, and warns you when the settings you picked make no sense.
CONVERSION
• Output formats: MP3, AAC, ALAC, FLAC, WAV, OGG, OPUS, VORBIS
• Input also accepts WavPack, AIFF, CAF, M4A and M4R
• Extract the audio track from video files
• Batch processing of individual files and whole folders
• A size forecast before you start — with a warning about pointless settings, such as re-encoding from lossy to lossless
QUALITY
• CBR and VBR, bitrate, sample rate and bit depth — for the formats that support them
• Resampling with a choice of algorithm quality, up to mastering grade and minimum phase
• Dithering with noise shaping: applied only when the bit depth actually drops
LOUDNESS
• EBU R128 normalization — per track or per album, targeting −23, −18 or −14 LUFS
• Your choice: write ReplayGain tags, or apply the gain to the audio itself
• Clipping protection and a manual ±dB gain
ANALYSIS
• A spectrogram of the whole file: zoom, panning, a choice of FFT window, PNG export
• Cutoff frequency detection, telling you when a "lossless" file was in fact made from a lossy source
• A live spectrum while you listen
PROCESSING
• Fade in and fade out
• Silence trimming at the start and at the end
• Mono downmix and single-channel selection
FILES AND METADATA
• Metadata preserved and carried over, artwork included
• Customisable filename templates and overwrite rules
• Output layout: by artist, by artist and album, everything in one folder, or keeping the original structure
INTERFACE
• Clean and minimal, fully translated into 14 languages: English, German, Russian, Spanish, French, Portuguese (Brazil), Italian, Japanese, Simplified Chinese, Korean, Dutch, Polish, Turkish and Swedish
Versionsverlauf
Klangbearbeitung hinzugefügt: Ein- und Ausblenden, Abschneiden der Stille an beiden Enden, manueller Gain, Zusammenlegen auf Mono und Auswahl eines einzelnen Kanals.
Auswahl der Resampling-Qualität hinzugefügt, dazu Dither: Er schaltet sich von selbst ein, sobald die Bittiefe wirklich sinkt.
AIFF als Ausgabeformat hinzugefügt, ebenso die durchschnittliche Bitrate (ABR) und die Profile HE-AAC und HE-AAC v2.
Das Spektrogramm kann jetzt echtes Zoomen mit Neuberechnung, die Wahl des FFT-Fensters, den Export als Bild und ein Live-Spektrum während der Wiedergabe.
Vorhersage der Dateigröße hinzugefügt, samt Warnungen vor sinnlosen Einstellungen wie lossy zu verlustfrei.
Prüfsummen SHA-256 und MD5 hinzugefügt, um zu bestätigen, dass die Quelldatei die richtige ist.
Einstellungen lassen sich als einzelne Datei exportieren und wieder importieren.
Konvertierung direkt aus der Zwischenablage: Symbol in der Menüleiste und ⌃⌥⌘C, ganz ohne Fenster.

• EBU R128 normalization, per track or per album, targeting −23, −18 or −14 LUFS.
• Your choice: write ReplayGain tags, or apply the gain to the audio itself.
