🔍 Overview

Musikai allows users to go from zero to publishing an album in digital music stores.

The steps to generate an album would be this:

1. Generate: use generate command to automatically generate hundreds of songs given a style or prompt.
2. Process: analyses the music to detect possible problems (long silences, unexpected BPM changes, etc), generating wave images, apply fade-outs and mastering the music.
3. Filter songs: Using the web app the user must approve the songs, with the help of the process data and the music itself. Every generated song has 2 endings, the best one being already selected, but it can also be changed.
4. Song titles: Song titles must be imported from an external csv or json file. The user can make them up or use external tools like ChatGPT.
5. Drafts: Album drafts with information such as title and optional subtitle and number of volumes must be also imported from an external csv or json file.
6. Covers: Cover generation takes titles from album drafts and uses midjourney to generate images.
7. Upscale covers: Once images are generated an upscale process uses Topaz Photo AI to upscale the images.
8. Filter covers: Using the web app the user must approve the covers.
9. Album generation: A command tool takes everything that has been generated and approved (songs, titles, drafts and covers) and generates albums.
10. Filter albums: Using the web app the user must approve the albums. Songs can be added or deleted during this process.
11. Publish: Albums are published to DistroKid automatically. In case you want to review before submitting, you can choose to press the button manually.
12. Sync: Once albums and songs are processed by DistroKid use sync command to obtain album UPC code and song ISRC codes and store them in the database.

🕹️ Commands

To see the list of available commands, run the following:

./musikai --help

To see the list of available options for a command, run the following:

./musikai {command} --help

These help commands will show you always the latest options and commands available. This README may be outdated, so it is recommended to use the help commands.

Common options

The following options can be found in most commands:

type (string)

This value is used to classify songs. It can be a just style like jazz, an identifier like jazz-test-01 or whatever you want. It is provided during the generation and then used to build the album or choose the DistroKid styles of the songs.

db-type (string) and db-conn (string)

• db-type (string): The type of the database. It can be postgres, mysql, or sqlite.
• db-conn (string): The connection string to the database. It must include the database name, the user, and the password. For sqlite, it must include the path to the sqlite file.

Example of a connection string for cockroachdb:

postgresql://my-username:[email protected]:26257/my-database?sslmode=verify-full

fs-type (string) and fs-conn (string)

• fs-type (string): The type of the file storage. It can be telegram, s3 or local.
• fs-conn (string): The connection string to the file storage.
  • For telegram: token@chat_id
  • For s3: key:[email protected]
  • For local: /path/to/directory

proxy (string)

The HTTP proxy to use. For example, http://localhost:3128. This is optional.

debug (bool)

If set to true, the application will output debug information.

Generate

The generate command is used to generate songs. You can specify the number of songs to generate, the account to use, the type of song, the prompt, and whether to use manual mode or not. If you use manual mode, the prompt will be directly used in the generation without applying any AI modifications to it.

Suno generates first a fragment of around 2 minutes. Udio generates first a fragment of around 30 seconds. Then you can extend this fragments multiple times. There are some parameters to control how this extensions are done:

• Duration of the song: min-duration and max-duration is used to continue extending or stop extending depending on the current total duration.
• Number of extensions: max-extensions forces to end the generation once the maximum number of extensions is reached.

Suno has a specific parameter to control the end of the song:

• Final style and lyrics: In order to tell suno that you want to end the song you have to explicitly indicate it in the lyrics and/or style section.
  • Parameters end-style, end-style-append and end-lyrics are applied when minimum duration is reached and it is the first extension.
  • Parameters force-end-style and force-end-lyrics are applied when minimum duration is reached and it isn't the first extension.

Udio needs a captcha resolver to bypass the captcha. You can use nopecha to solve the captcha manually or 2captcha to use a service to solve the captcha. Captcha providers connect to your computer using a proxy. The tool starts a local server that the captcha provider connects to. You need to have ngrok installed in your computer so the tool can expose the local server to the captcha provider. You can avoid this by using the same proxy both in proxy and captcha-proxy.

Suno

You need to configure a Suno account to generate songs

You need to capture the cookie from Suno website.

1. Go to https://suno.com/
2. Login if you are not already logged in
3. Open the developer tools (F12)
4. Go to the "Network" tab
5. Refresh the page
6. Click on the first request to https://clerk.suno.com/v1/client?_clerk_js_version=4.70.1
7. Go to the "Request Headers"
8. Copy the "cookie" header

Then you must store the cookie in your database. You can use the command setting to store the cookie in the settings table. Pass the cookie as the value and choose a name for the account.

./musikai setting --config cookie.yaml

# cookie.yaml
debug: false
db-type: see common options
db-conn: see common options
service: suno
account: accountname
value: cookievalue

Udio

You need to configure a Udio account to generate songs

You need to capture the cookie from Udio website.

1. Go to https://www.udio.com/
2. Login if you are not already logged in
3. Open the developer tools (F12)
4. Go to the "Network" tab
5. Refresh the page
6. Click on the first request to https://www.udio.com/api/users/current
7. Go to the "Request Headers"
8. Copy the "cookie" header

Then you must store the cookie in your database. You can use the command setting to store the cookie in the settings table. Pass the cookie as the value and choose a name for the account.

./musikai setting --config cookie.yaml

# cookie.yaml
debug: false
db-type: see common options
db-conn: see common options
service: udio
account: accountname
value: cookievalue

Captcha resolver

Udio needs a captcha resolver to bypass the captcha. You can use either https://nopecha.com or https://2captcha.com as the captcha provider. Create an account in any of the services and obtain the API key.

# settings to be added to generate.yaml
captcha-key: captcha-service-key
captcha-provider: nopecha # nopecha or 2captcha

Ngrok tunnel

The captcha provider needs a way to connect to your computer. This is because both the requests to udio and requests to the captcha provider must come from the same IP address. By default it will use ngrok to expose a local server to the internet.

To install ngrok, go to https://ngrok.com/download and follow the instructions. You also need to create an account in ngrok and obtain the authtoken. To authenticate with ngrok, go to https://dashboard.ngrok.com/get-started/your-authtoken and copy the token.

ngrok authtoken your-authtoken

Alternatively, you can use a proxy to connect to the captcha provider. The proxy must be accessible from the internet and must be used in the proxy option as well as in the captcha-proxy option.

# settings to be added to generate.yaml
proxy: http://my-proxy.com
captcha-proxy: http://my-proxy.com

DistroKid

You need to configure a DistroKid account to publish albums.

You need to capture the cookie from DistroKid website.

1. Go to https://distrokid.com/profile
2. Login if you are not already logged in
3. Open the developer tools (F12)
4. Go to the "Network" tab
5. Refresh the page
6. Click on the request to https://distrokid.com/profile/
7. Go to the "Request Headers"
8. Copy the "cookie" header

Then you must store the cookie in your database. You can use the command setting to store the cookie in the settings table. Pass the cookie as the value and choose a name for the account.

./musikai setting --config cookie.yaml

# cookie.yaml
debug: false
db-type: see common options
db-conn: see common options
service: distrokid
account: accountname
value: cookievalue

Midjourney

You need to configure a Midjourney account to generate covers. Musikai uses bulkai under the hood to generate the covers.

To generate a session file for midjourney, you need first to install bulkai and then run the following command:

go install github.com/igolaizola/bulkai/cmd/bulkai@latest
bulkai create-session

This will create a session.yaml file in the current directory. You can use this file in the cover command.

Database

Both postgres and mysql are supported. SQLite is also supported but it is not recommended for production.

Once you have choosen your database provider you must create a database and a user with read/write access to the database.

CREATE DATABASE IF NOT EXISTS musikai;
CREATE USER IF NOT EXISTS musikai WITH PASSWORD 'P@ssw0rd!';
GRANT ALL ON DATABASE musikai TO musikai;

Your db-type setting must match your database provider (postgres, mysql, sqlite). Your db-conn setting must match your database connection string, and must include the database name, the user, and the password.

Here is an example of a connection string for postgres:

postgresql://musikai:P@[email protected]:26257/musikai?sslmode=verify-full

Once you have created your database, you can use the migrate command to create the tables.

./musikai migrate --db-type {postgres,mysql,sqlite} --db-conn {connection-string,sqlite-file}

File storage

Local storage

Local storage can be used to store the generated assets in any directory in your filesystem. You can even use a google drive folder, a dropbox folder, or any other folder that is mounted in your filesystem.

fs-type: local
fs-conn: /path/to/directory

Telegram storage

Telegram storage can used to store the generated assets in a telegram chat. Use t.me/botfather to create a bot and obtain the token. Then create a chat with the bot and obtain the chat id. You can obtain the chat id by opening the chat on web.telegram.org and looking at the URL. The chat id is the number after https://web.telegram.org/a/#.

fs-type: telegram
fs-conn: token@chat_id

S3 storage

S3 storage can be used to store the generated assets in an AWS S3 bucket.

fs-type: s3
fs-conn: key:[email protected]

Here is a guide to create a bucket on AWS and obtain credentials.

Create a bucket

1. Go to Buckets: https://s3.console.aws.amazon.com/s3/buckets
2. Click Create bucket
3. Choose a name and region. For example, "musikai-s3" and "Europe (Frankfurt) eu-central-1"
4. Click Create bucket

Obtain credentials

1. Go to "Identity and Access Management (IAM)": https://eu-central-1.console.aws.amazon.com/iamv2
2. Select "Users" from "Access Management"
3. Click "Add users"
4. Choose a name and click Next. For example, "musikai-s3-service"
5. Select "Attach policies directly" and choose "AmazonS3FullAccess"
6. Click Next and then Create user
7. Click on the user name you just created
8. Click on "Security credentials" tab
9. Click on "Create access key"
10. Select "Application running outside AWS".
11. Add a description and click "Create access key". For example "musikai-s3-service-key"
12. Copy the "Access key ID" and "Secret access key" and save them in a safe place.
