Suno AI Tutorial Part 3: Audio Referencing, Extending & Pro Exports

The last video in the Suno training series covers everything around the advanced panel: what material can be brought into a track before it is generated, and what can be done with a track once it exists. Rohan Vijayakumar walks through both sides of that panel, from attaching audio and voices to exporting finished stems.

Bringing your own material in

Above the lyrics box sit three buttons that control what gets attached to a generation. Add audio takes a file by browsing, uploading, or recording directly. Add voice picks a saved voice, and inside that picker is a still-beta option to create a voice by recording or uploading at least ten seconds of singing in a quiet spot, ideally with a decent microphone though a laptop mic works. Add inspo points at one of your own playlists, using only your own music as a reference. Attaching audio directly replaces the inspo option, since the attached track itself becomes the reference at that point.

The sounds tab

A third tab, sounds, does not generate full songs. It generates short samples, effects, loops, and one-shots from a single field describing the sound wanted, with advanced options limited to three controls: choosing a one-shot or a loop, and setting BPM and key, both of which can be left on automatic.

What happens after a track is generated

Every generated track carries a three-dot menu where everything after generation happens. Five entries open a submenu: remix, edit, share, download, and manage. Five more act immediately: publish, queue, add to a playlist, start a radio station, or send to the trash. Remix and edit look similar but do different things. Remix creates a new song built from the original, such as a cover in a different genre, a mashup, or a sample. Edit changes the existing song itself, through options like extending it, cropping it, removing a section, reversing it, or slowing it down. Picking any of the edit options reopens the advanced panel with the track already attached.

Using the extend tool

Extend is the option used most often. Selecting it loads the track into the advanced panel as attached audio with the mode already set to extend, and the waveform splits into two parts, the portion that stays and the portion Suno will recreate. Dragging the boundary between those two parts sets where the new material begins, and pressing create generates the extension from that point.

Exporting the finished file

Download offers four choices. MP3 is the plain option and needs nothing extra, the file to hand off for most purposes. WAV provides a lossless master. Stems splits the track into its individual parts. Video renders the track as a video file suitable for posting. The WAV, stems, and video options all carry a pro badge.

Key takeaways

• Three buttons above the lyrics box, add audio, add voice, and add inspo, control what material gets attached to a generation before it runs.
• Creating a custom voice needs at least ten seconds of recorded or uploaded singing, ideally in a quiet space.
• The sounds tab generates short samples, loops, and one-shots rather than full songs, with BPM and key controls that can be left on automatic.
• Remix builds a new song from an existing one, while edit changes the existing song directly through options like extend, crop, remove, reverse, or slow down.
• Downloads offer MP3 as the plain export, with WAV masters, individual stems, and video renders available under the pro badge.

Who this is for

This is for Suno users who have already made songs in simple and advanced mode and are ready to bring their own audio or voice into a track, then extend, remix, or export a finished file at a professional quality level.
