Prerequisites
- A computer or mobile device with internet access

- Basic understanding of uploading audio files
- No musical training needed
- Time commitment: 5-15 minutes per song
Why Suno v4.5+ Works Better
Suno v4.5+ delivers what CEO Mikey Shulman calls “a glimpse of the future.” The model produces much clearer vocals and richer sound quality compared to previous versions. As one reviewer noted: “I can’t tell that’s AI generated. That’s what’s getting quite scary about this.”
Unlike other AI music tools that only work with text prompts, Suno v4.5+ lets you upload your own audio files and build on them. The model supports a wide range of music genres to choose from. This means you can start with a simple voice recording and turn it into a full production, or take an instrumental track and add professional vocals.
Step-by-Step instructions for Suno v4.5+
Step 1: Access Suno v4.5+ features
Log into your Suno Pro account and look for the red “v4.5+” indicator at the top of the interface. This model supports up to 8 minutes of audio generation, which is perfect for full-length songs.
Pro tip: Make sure you’re using the Pro version, as v4.5+ features are only available to paid subscribers.
Step 2: Choose your creation method
Upload an audio (your vocals or an instrumental track).
After you have three main options:
- Add Vocals: Start with an instrumental and layer vocals on top
- Add Instrumentals: Begin with a voice recording and add backing music
- Inspire: Create songs based on your playlist vibes
Pro tip – Advanced Options: Look for the “Advanced Options” section (marked with a “NEW” tag) where you can fine-tune your creations:
- Vocal Gender: Choose between male or female vocals directly
- Weirdness: Control how experimental or conventional your output sounds (0-100% scale)
- Style Influence: Adjust how strongly the AI follows your style prompts (0-100% scale)
These controls give you much more precision over the final result, especially when you want consistent vocal characteristics or need to dial in the perfect balance between creativity and your intended style.
Common pitfall: Don’t try to use the Inspire feature with too many songs at once. Start with 1-2 tracks for better results.
Step 3: Generate your track
Hit the “Create” button and wait for the AI to work its magic. The generation process is much faster than previous versions, usually taking under a minute.

Troubleshooting Guide
Issue 1: “Topic too long” error message
Solution: Shorten your style description or prompt text. The system has limits on text length.
Issue 2: Generated music doesn’t match your uploaded audio style
Solution: Try using fewer reference tracks in your playlist or be more specific with your style descriptions.
Issue 3: Audio quality sounds muffled
Solution: Make sure your original recording is clear and recorded in a quiet environment.
