Yet Another Audio Stream Recorder

Audio stream recorded and static DB for radio stations.
Why? Because other tools are (probably, is not clear) not availabe to use.

Install

Install with pip

pip install yaasr

Usage

From Python

Save predefined audio locally

Load a pre-defined stream and save 5 audio chunks of 60 seconds

from yaasr.recorder.stream import YStream

ys = YStream('radio-universidad-cordoba-argentina')
ys.load()
ys.record(total_seconds=300, chunk_bytes_size=1024, chunk_time_size=60)

You will see new audio files at your local folder

Save custom audio locally

Load a custom stream and save 5 audio chunks of 60 seconds

from yaasr.recorder.stream import YStream

""" test custom stream """
ys = YStream(stream_name='my-custom-stream')
ys.destination_folder = 'some-path/my-chunks-folder'
ys.title = 'My radio title'
ys.short_name = 'my-radio'

# list of stream (if first fails the second should be used)
ys.streams = [
    {'url': 'https://my-radio.org/stream'}
]

ys.record(total_seconds=300, chunk_bytes_size=1024, chunk_time_size=5)

You will see new audio files at some-path/my-chunks-folder folder

Upload to Google Cloud Storage

from yaasr.recorder.stream import YStream
from yaasr.processors.audio.reduce import reformat
from yaasr.processors.archive.google_cloud import upload_to_google_cloud_storage

# os.environ["GOOGLE_APPLICATION_CREDENTIALS"] = "google-cloud-storage-credential.json"
ys = YStream('radio-universidad-cordoba-argentina')
ys.load()

# post-processors (you can combine or create new processors)
ys.post_process_functions = [
    {
        'fn': reformat,
        'params': {
            'audio_format': 'mp3',
            'mono': True,
            'delete_on_success': True
        }
    },
    {
        'fn': upload_to_google_cloud_storage,
        'params': {
            'bucket_name': 'parlarispa-radio',
            'delete_on_success': True
        }
    }
]
ys.record(total_seconds=300, chunk_bytes_size=1024, chunk_time_size=60)

Upload audio chunks using ssh

Post process audio to MP3 16Khz and upload via ssh the result cleaning local files after the process

from yaasr.recorder.stream import YStream
from yaasr.processors.audio.reduce import reformat
from yaasr.processors.archive.ssh import upload_ssh


ys = YStream('radio-universidad-cordoba-argentina')
ys.load()

# post-processors (you can combine or create new processors)
ys.post_process_functions = [
    {
        'fn': reformat,
        'params': {
            'audio_format': 'mp3',
            'delete_on_success': True
        }
    },
    {
        'fn': upload_ssh,
        'params': {
            'host': 'myhost.com',
            'user': 'username',
            'password': 'mypass',
            'destination_folder': '/home/username/audios/',
            'port': 901,
            'delete_on_success': True
        }
    }
]
ys.record(total_seconds=300, chunk_bytes_size=1024, chunk_time_size=60)
