WAV till MP3 Vanliga frågor om konvertering
How do I convert WAV audio to MP3 without quality loss?
+
Upload the WAV file and our converter chooses the MP3 codec / bitrate combination that matches the source. Lossless target (MP3 = WAV / FLAC / ALAC) preserves every sample; lossy target (MP3 = MP3 / AAC / OGG) defaults to 192 kbps which is transparent for spoken-word audiobooks and most music.
What bitrate does the MP3 file use?
+
Default is 192 kbps for lossy MP3; pass-through for lossless MP3. Override to 320 kbps for audiophile or 64-96 kbps for spoken-word audiobooks (transparent for voice, halves the file size).
Will going from WAV to MP3 reduce my audio quality?
+
If WAV is lossy and MP3 is lossless (e.g. MP3 → WAV), the MP3 file is no better than the WAV — you can't recover information that's already been thrown away. If WAV is lossless and MP3 is lossy, expect the MP3 codec to recompress; at 192 kbps this is transparent for most content.
Does the WAV to MP3 converter keep ID3 / metadata tags?
+
Yes — title, artist, album, year, track number, album art, and chapter markers (important for audiobooks) are read from WAV and written into the MP3 container where the MP3 format supports tags. M4B audiobook structure round-trips into M4B and AAX → M4B output.
Can I batch convert hundreds of WAV files to MP3?
+
Yes — drop a folder of WAV files in and we process them in parallel. Premium has more parallel workers and no per-file size cap, so a 500-file batch finishes in minutes rather than tens of minutes.
Will the MP3 keep the same sample rate as WAV?
+
By default yes (48 kHz WAV → 48 kHz MP3). If you need to downsample for compatibility (e.g. 96 kHz → 44.1 kHz for CD burning) the advanced sample-rate option does this with high-quality resampling.
Can I normalize loudness in the WAV to MP3 step?
+
Yes — the loudness-normalize option applies ITU-R BS.1770 / EBU R128 normalization to the MP3 output, targeting -14 LUFS (streaming standard), -16 LUFS (podcast standard), or -23 LUFS (audiobook standard). Useful when batch-converting tracks with varying mastering levels.
Will the MP3 play on my car stereo / iPod / audiobook app?
+
MP3 plays universally. AAC plays on Apple, most Android, Sonos. FLAC plays on Sonos and Android, less well on older iPods. M4B audiobooks play with chapter navigation on iOS Books, Audiobookshelf, and Smart Audiobook Player. The advanced options include device presets.
Is my WAV file private during conversion?
+
Yes — uploaded WAV files are processed in isolated workers and deleted within minutes. We never play, store, or share the audio content. Especially important when working with personal audiobook libraries.
How long does converting a 10-hour audiobook WAV to MP3 take?
+
Same-codec re-mux: 10-30 seconds. Re-encode to a different codec: typically 10-20% of source duration, so a 10-hour audiobook finishes in 60-120 minutes. Chapter markers survive the round-trip and split cleanly.
Why is the MP3 file louder / quieter than the WAV source?
+
No automatic gain change happens unless you turn on the normalize option. If you do see a level change, your audio player or media library may be applying ReplayGain or per-track normalization on playback — not us.
Can I convert DRM-protected WAV downloads to MP3?
+
No — DRM-encrypted WAV (Audible AAX with personal activation, Apple Music) is encrypted at the bit level and we can't process it. Sources from public-domain audiobook archives, your own recordings, or Bandcamp downloads convert fine.
