master_song | Opens the Bandmixr studio in the chat to master or enhance a finished song (a stereo mix). The song is checked in the browser for loudness, peaks, stereo image and tonal balance, and a 30-second mastered preview plays next to the original. Mastering the full song needs a Bandmixr account. params: preset, genre |
check_mix | Opens the Bandmixr Mix Analyzer in the chat. It checks a mix or master in the browser (the file is not uploaded): loudness (LUFS), true peak, clipping, stereo image and tonal balance, with a verdict for each and a 30-second mastered preview. params: genre |
get_analyzer_session | Returns a 30-minute ticket and the address of the Bandmixr preview service, which the studio in the chat uses for the 30-second mastered preview. The studio calls this tool on its own; the assistant does not need to call it directly. params: none |
get_account | Shows the connected Bandmixr account's plan and its limits (stems per song, song length, storage). Needs the person to connect their Bandmixr account. params: none |
list_songs | Lists the person's Bandmixr songs, most recently changed first. params: none |
get_song_status | One song's stems with their labels, uploads and analysis still running, whether the person has confirmed the labels, and where the mix and master stand. params: songId* |
create_song | Creates a new song in Bandmixr for mixing stems and opens the studio with its upload box. The genre and the mastering style are the ones the person names (other and streaming when they name none). Mixing and mastering are part of it: they start by themselves once the stems are uploaded and the person has confirmed the labels in the studio. params: title, genre, preset, mix |
update_song | Changes the title or the genre of a song (not while it is being mixed). params: songId*, title, genre |
open_song_studio | Opens the Bandmixr studio for a song in the chat. It shows what the song needs next: the upload box for stems, the label check (only the person can confirm labels there), the mix progress, or the player with the original, the mix and the master. params: songId* |
get_song_session | Returns a 15-minute ticket for one of the person's songs, which the studio in the chat uses to upload stems, show the label check and the progress, and play the original, the mix and the master. The studio calls this tool on its own; the assistant does not need to call it directly. params: songId* |
prepare_full_master | Creates a new song named after the file the person checked in the studio and returns a short-lived ticket for uploading it, so the studio can upload and master the full song. The studio calls this tool when the person chooses to master the full song; the assistant does not need to call it directly. params: title*, genre |
set_stem_labels | Sets what is on each stem from what the person says about their files (stem ids and file names come from get_song_status). It does not confirm the labels: the person still confirms them with "Labels are correct" in the studio before anything is mixed. params: songId*, labels* |
mix_and_master | Mixes an existing song's stems and masters the mix in one go (draft, final mix, master), for example to mix it again with another genre or mastering style; a song made with create_song is already set up for this. It waits for the uploads, the analysis and the person's "Labels are correct" in the studio, then starts by itself. The mastering style is the one the person names (streaming when they nam params: songId*, preset, master |
start_mastering | Masters the song's finished mix, or masters it again in another style (for example "louder": loud). The song needs a finished mix, from mix_and_master or an uploaded mix. The studio shows the progress and plays the new master, which replaces an earlier master made in the chat (downloaded ones stay). params: songId*, preset* |
adjust_mix | Changes a song mixed from stems the way the person asks after listening: a stem louder or quieter, muted or back in, more or less reverb, or placed left, center or right. One call takes all the changes for a song. Bandmixr then makes the mix and the master again with the changes (about as long as the first mix); the studio shows the progress and plays the new version, which replaces the earlier ve params: songId*, changes*, preset |
