MP3 in het kort
MP3
MP3 conversion is necessary when universal device compatibility is non-negotiable.
Convert to MP3 for podcasts distributed through iTunes, Spotify, and all major platforms.
MP3 is essential for audio files that will be used on in-vehicle entertainment systems, car stereos, or older consumer devices.
If your audience uses phones from any era, MP3 guarantees playback without format compatibility issues.
Choose MP3 for personal music libraries that must be accessible on legacy devices, portable players, and car systems.
MP3 is ideal for archiving audio where you want absolute certainty the file will be playable for decades.
Music production professionals often maintain MP3 versions of masters alongside higher-quality formats for distribution and preview purposes.
AMR in het kort
AMR
Convert to AMR when the target is a speech-oriented mobile or telephony workflow, such as voicemail systems, call recordings, or compatibility with older handset ecosystems.
It is useful when bandwidth and voice intelligibility matter more than music quality.
For music or general listening, AAC, Opus, or WAV are better targets.
