Frequently asked questions
What is Discord's file size limit for audio?+
Free Discord accounts can upload files up to 8MB. Nitro Basic raises this to 50MB. Nitro (full subscription) allows up to 500MB. Server boosts can raise the limit for all members in that server. Check your server's upload limit if your file is between these thresholds.
Should I use Opus or MP3 for Discord audio?+
For voice messages and speech, use Opus at 32–64 kbps — it sounds significantly better than MP3 at the same bitrate for voice. For music clips, MP3 at 192–320 kbps generally sounds better than Opus at equivalent file sizes for complex harmonic content. Discord's own voice channels use Opus internally.
Can Discord bots play audio files directly?+
Yes — Discord bots using the discord.js or Discord.py libraries can play audio files from URLs or local buffers. Common audio formats for bots: Opus in WebM container (native to Discord voice protocol), MP3, or FLAC. The discord.js voice package handles format conversion internally for MP3 playback.
