Suno Premier's 30-minute upload versus Sume's audio limits

Suno's pricing page lists audio uploads of up to 30 minutes on Premier ($24 a month, $19.20 a month billed annually). Sume's limits are different in kind: Timeline audio outputs up to 1,800 seconds (also 30 minutes), audio detach reads sources up to 1,800 seconds and outputs up to 900, and speech-to-text jobs run up to 10 minutes.

The limits side by side

Different jobs

Suno's upload feeds its own generation and Studio tools, which Premier unlocks with MIDI, effects and automation. Sume's endpoints are separate calls: pull audio from a video at $0.01, join or split at $0.01 per job, transcribe at $0.01 per audio minute.

• A 30-minute track at STT is three 10-minute jobs.
• Detach output capped at 900 s means a 30-minute source needs two ranges.
• Joined output may reach 1,800 s.

Splitting for STT

Timeline audio split takes 1 to 20 ranges, so a 30-minute file becomes three 600-second parts for $0.01, and transcribing 30 minutes is 30 x $0.01 = $0.30 in speech-to-text.

Where the fields are documented

The split call takes operation, one url and ranges[], each range being start and an optional end. See the Timeline audio docs.
