Songs, Jingles and Lyric Videos Guide

Overview

Asteria Engine composes new music for your workspace:

• songs with singing, for example a jingle, an anthem for a launch or a song about your town
• instrumentals: soundtracks, intros and background beds
• sound effects

Everything you compose is saved in the Music Library. You can use it in your posts and videos, and turn a sung song into a lyric video.

Compose a Song

1. Open Music Library and select Compose music. Or, from the dashboard, choose A song or jingle, or ask the AI assistant.
2. Choose Song / music.
3. Say whether it is a song with singing or an instrumental. Asteria always asks, because they are different things.
4. Write the Creative brief: what the song is about, who it is for and how it should feel. You can speak it with the microphone button.
   • Genre and Mood are optional.
   • Get new ideas suggests fresh song ideas based on your workspace.
5. Choose the voices:
   • one Lead vocalist, or Multiple vocalists
   • with multiple vocalists, choose the lead and any complementary, backing or bridge voices
   • with a music vocal profile, the generated singers follow its range and delivery
6. Choose the Duration and select Write the song.

Asteria then shows the song before anything is charged:

• The feeling, The hook and The sound: what the song is going for.
• The lyrics: change any word, name or detail, or the title.
  • Keep the [Verse] and [Chorus] tags.
  • Words in (brackets) are sung by backing vocals.
  • If the lyrics included instructions to the band, they are listed under Played, not sung. They shape the arrangement instead of being sung.
• Rewrite asks for a new version, and Back to brief lets you change the brief.

When you are happy, check the render cost and select Compose this song. The track appears in the Music Library when it is ready.

Compose an Instrumental or Sound Effect

For an instrumental, choose Song / music, then the instrumental option. Then pick a Music engine:

• Lyria (Google's music model) for the richest arrangements, up to 3 minutes.
• Stable Audio for long, steady beds up to 6 minutes, for walkthroughs, streams and podcasts.

For a sound effect, choose Sound effect and describe the sound, for example "a soft paper swoosh" or "a till drawer opening".

Music Vocal Profiles

A vocal profile guides the range, texture and delivery of the generated singers.

1. In the Music Library, open Vocal profiles and select Create vocal profile.
2. Record a guided 30–45 second sample. Sing comfortably: start gently, repeat with more energy, then hold the final word.
3. Confirm you have the right to use this voice for AI-generated music.
4. Review What Asteria heard and correct any wording before saving.

Choose a profile as your default, or pick one each time you compose.

The singers are always new voices that follow the profile's direction. A profile does not copy the recorded person's voice.

Use a Track

Each ready track in the Music Library has these actions:

• Add song to post: choose a post and the track becomes its audio.
  • If the post already has a video, its audio is changed.
  • If it has pictures, an audio reel is made from them.
• Create visuals: opens a Studio video session built around the track. The cuts, movement and energy follow its timing, and the track stays as the audio.
• Lyric video: available on sung tracks with lyrics (see below).
• Download.
• Edit audio: choose where the track starts and how long it runs, then save it as a new track or replace the original.

You can also Upload audio that you have the rights to use.

Make a Lyric Video

A lyric video shows the song's words on screen in time with the singing.

1. On a sung track, select Lyric video.

2. Choose the Shape:

   • Vertical 9:16 for Reels, TikTok and Shorts
   • Portrait 4:5 for the Instagram feed
   • Square 1:1
   • Landscape 16:9 for YouTube and websites

3. Choose what goes behind the words:

   • Words only: bold type on your brand colours. No credits.

   • Pictures: pictures behind the words, your own, drawn for the song, or both. Credits only for drawn pictures.

   • Video: generated footage behind the words. The cost is shown before you start.

   • With Pictures, add your own backdrops or describe what the drawn pictures should show, and choose an art style. If your own pictures cover the whole song, nothing is drawn.

   • With Video, describe what the footage should show. Left empty, it follows the song's own story.

   • For each of your own pictures, choose where it appears: verses, chorus, bridge or anywhere.

   • To feature people in the drawn pictures or footage, choose photos of them from your media. Use adults only, and only photos you have the right to use.

4. Lettering is matched to the song: Asteria picks the typeface, colours and how each word lights up from the song's genre and mood.

5. Start it. Progress shows on the track; filming footage takes several minutes.

When it is ready, add it to a post or save it to your Media Library.
