# Evolution Audio Converter
|
||||
|
||||
This project is a microservice in Go that processes audio files, converts them to **opus** or **mp3** format, and returns both the duration of the audio and the converted file in base64. The service accepts audio files sent as **form-data**, **base64**, or **URL**.

|

|
||||
### Storage Options
|
||||
|
||||
The service supports two storage modes for the converted audio:
|
||||
|
||||
1. **Base64 (default)**: Returns the audio file encoded in base64 format
|
||||
2. **S3 Compatible Storage**: Uploads to S3-compatible storage (AWS S3, MinIO, etc.) and returns a presigned URL
|
||||
|
||||
When S3 storage is enabled, the response will include a `url` instead of the `audio` field:
|
||||
|
||||
```json
|
||||
{
|
||||
"duration": 120,
|
||||
"format": "ogg",
|
||||
"url": "https://your-s3-endpoint/bucket/file.ogg?signature...",
|
||||
"transcription": "Transcribed text here..." // if transcription was requested
|
||||
}
|
||||
```
|
||||
|
||||
If S3 upload fails, the service automatically falls back to base64 encoding.
|
||||
|
||||
## Running the Project

|
||||
docker run -p 4040:4040 --env-file=.env audio-service
|
||||
```
|
||||
|
||||
This will start the container on the port specified in the `.env` file.
|
||||
|
||||
## How to Use
|
||||
|
||||
You can send `POST` requests to the `/process-audio` endpoint with an audio file in the following formats:
|
||||
|
||||
- **Form-data** (to upload files)
|
||||
- **Base64** (to send the audio encoded in base64)
|
||||
- **URL** (to send the link to the audio file)
|
||||
## API Usage
|
||||
|
||||
### Authentication
|
||||
|
||||
All requests must include the `apikey` header with the value of the `API_KEY` configured in the `.env` file.
|
||||
All requests must include the `apikey` header with your API key.
|
||||
|
||||
### Optional Parameters
|
||||
### Endpoints
|
||||
|
||||
- **`format`**: You can specify the format for conversion by passing the `format` parameter in the request. Supported values:
|
||||
- `mp3`
|
||||
- `ogg` (default)
|
||||
#### Process Audio
|
||||
|
||||
### Audio Transcription
|
||||
`POST /process-audio`
|
||||
|
||||
You can get the audio transcription in two ways:
|
||||
Accepts audio files in these formats:
|
||||
|
||||
1. Along with audio processing by adding the `transcribe=true` parameter:
|
||||
- Form-data
|
||||
- Base64
|
||||
- URL
|
||||
|
||||
Optional parameters:
|
||||
|
||||
- `format`: Output format (`mp3` or `ogg`, default: `ogg`)
|
||||
- `transcribe`: Enable transcription (`true` or `false`)
|
||||
- `language`: Transcription language code (e.g., "en", "es", "pt")
|
||||
|
||||
#### Transcribe Only
|
||||
|
||||
`POST /transcribe`
|
||||
|
||||
Transcribes audio without format conversion.
|
||||
|
||||
Optional parameters:
|
||||
|
||||
- `language`: Transcription language code
|
||||
|
||||
### Example Requests
|
||||
|
||||
#### Form-data Upload
|
||||
|
||||
```bash
|
||||
curl -X POST -F "file=@audio.mp3" \
|
||||
-F "format=ogg" \
|
||||
-F "transcribe=true" \
|
||||
-F "language=en" \
|
||||
http://localhost:4040/process-audio \
|
||||
-H "apikey: your_secret_api_key_here"
|
||||
```
|
||||
|
||||
2. Using the specific transcription endpoint:
|
||||
#### Base64 Upload
|
||||
|
||||
```bash
|
||||
curl -X POST -F "file=@audio.mp3" \
|
||||
-F "language=en" \
|
||||
http://localhost:4040/transcribe \
|
||||
curl -X POST \
|
||||
-d "base64=$(base64 audio.mp3)" \
|
||||
-d "format=ogg" \
|
||||
http://localhost:4040/process-audio \
|
||||
-H "apikey: your_secret_api_key_here"
|
||||
```
|
||||
|
||||
Optional parameters:
|
||||
- `language`: Audio language code (e.g., "en", "es", "pt"). If not specified, it will use the value defined in `TRANSCRIPTION_LANGUAGE` in `.env`. If neither is defined, the system will try to automatically detect the language.
|
||||
#### URL Upload
|
||||
|
||||
The response will include the `transcription` field with the transcribed text:
|
||||
|
||||
```json
|
||||
{
|
||||
"transcription": "Transcribed text here..."
|
||||
}
|
||||
```bash
|
||||
curl -X POST \
|
||||
-d "url=https://example.com/audio.mp3" \
|
||||
-d "format=ogg" \
|
||||
http://localhost:4040/process-audio \
|
||||
-H "apikey: your_secret_api_key_here"
|
||||
```
|
||||
|
||||
When used with audio processing (`/process-audio`), the response will include both audio data and transcription:
|
||||

|
||||
