∙ ID3ED (ID3 - Encoder - Decoder)

⚬ Library for encoding/decoding ID3 tags

Under construction !

Project status

Right now it`s capable of reading and writing ID3v1 and ID3v1.1 tags.

ID3v2 support is still in making, but it can read header and frames

∙ Installation

To download package source:

go get github.com/Unbewohnte/id3ed/...

will be deprecated in 1.17 as far as I know

To donwload and compile package:

go install github.com/Unbewohnte/id3ed/...

∙ Examples

⚬ Reading ID3v1

package main

import(
    "fmt"
    id3v1 "github.com/Unbewohnte/id3ed/v1"
)

func main() {
    mp3file, err := os.Open("/path/to/mp3/myMP3.mp3")
    if err != nil {
        panic(err)
    }

    // extract ID3v1.1 tag 
    mp3tag, err := id3v1.Readv1Tag(mp3file)
    if err != nil {
       panic(err)
    }

    // print the whole tag
    fmt.Printf("%+v",mp3tag)

    // get certain fields
    songname := mp3tag.SongName

    genre := mp3tag.Genre

    // etc.
}

⚬ Writing ID3v1

package main

import(
    "fmt"
    id3v1 "github.com/Unbewohnte/id3ed/v1"
)

func main() {
	f, err := os.OpenFile("/path/to/file/myfile.mp3",os.O_WRONLY, os.ModePerm)
	if err != nil {
		panic(err)
	}
	defer f.Close()

    // create your tags struct
	tag := &id3v1.ID3v1Tag{
            SongName: "mysong",
            Artist:   "me",
            Album:    "my album",
            Year:     2021,
            Comment:  "Cool song",
            Track:    1,
            Genre:    "Christian Gangsta Rap", // for list of genres see: "./v1/genres.go"
	}

    // write tags to file
	err = tag.WriteToFile(f)
	if err != nil {
		panic(err)
	}
}

⚬ Reading ID3v2

package main

import(
    "fmt"
    id3v2 "github.com/Unbewohnte/id3ed/v2"
)

func main() {
    mp3file, err := os.Open("/path/to/mp3/myMP3.mp3")
    if err != nil {
        panic(err)
    }

    // extract ID3v2 tag 
    mp3tag, err := id3v2.Readv2Tag(mp3file)
    if err != nil {
       panic(err)
    }

    if mp3tag.Header.Version == id3v2.V2_3 {
        // get certain frame by identifier
        title := mp3tag.Frames["TIT2"]
        artist := mp3tag.Frames["TPE1"]
    }


    // etc.
