Python - Alsaaudio - PTT

mumai · 4. Juni 2023

Hallo,
ich habe eine spez. Frage an euch Experten. Ich habe im Netz ein kleines Tool gefunden, das es mir erlaubt bei einem gefundenen Audiosignal meiner Soundkarte bei dem RS232 Adapter die PTT auf einem RTS Pin zu schalten. Das funktioniert soweit recht gut. Habe das Script etwas angepasst und einige Passagen verändert, das er sofort die Schaltung bei dem kleinsten Audiosignal schaltet.

Nun ist es so, das ich gerne möchte, das ich im Script oben eine von mir bereitgestellte Audio Datei (WAV, oder MP3) in einer Variabel angebe, und diese nach einer von mir vordefinierten Zeit in Sekunden bei einem nicht registrierten Audiosignal an das Mikrofon (Audioausgang) sendet und zusätzlich dabei den RTS Pin schaltet und beim Ende der Audiodatei die PTT schaltung storniert und das aussenden unterbricht. Wie kann ich das umsetzen? Hier mal der Codeschnipsel:

Python:

#!/usr/bin/python
import tkinter as tk
import alsaaudio, time, audioop
import serial

# COM Port
com = '/dev/ttyUSB1'
# Level wann auf Durchgang geschalten wird
dbm = 0
# Sendeverzoegerung
svz = 3
# PTT nach Level halten
lvl = 100
# Sende und Empfangslevel
rx = 0
tx = 0

ser = serial.Serial(str(com), baudrate = 9600, timeout = 3.0)
audio = alsaaudio.PCM(alsaaudio.PCM_CAPTURE, alsaaudio.PCM_NONBLOCK)
audio.setformat(alsaaudio.PCM_FORMAT_S16_LE)
audio.setperiodsize(160)
audio.setchannels(1)
audio.setrate(8000)

def update():
 global rx
 global tx

 a, data = audio.read()
 if audioop.avgpp(data, 1) > dbm:
  tx = tx + 2
  if tx > svz:
   tx = tx - 1
   rx = 0;
   oled_d.config(text = 'PTT: An', fg = 'red')
   ser.setDTR(1)
   ser.setRTS(1)
 else:
  rx = rx + 2
  if rx >= lvl:
   rx = rx - 1
   tx = 0
   oled_d.config(text = 'PTT: Aus', fg = 'green')
   ser.setDTR(0)
   ser.setRTS(0)

 # Setze Fensterinhalte
 oled_a.config(text = 'Zeile 1', fg = 'grey')
 oled_b.config(text = '----------------------------------------------------------------------------------', fg = 'grey')
 oled_c.config(text = 'Level max: ' + str(dbm) + ' db   -   Signal: ' + str(audioop.avgpp(data, 1)) + ' db', fg = 'black')
 oled_e.config(text = '----------------------------------------------------------------------------------', fg = 'grey')
 oled_f.config(text = 'Zeile 5', fg = 'grey')

 # Ruhe
 time.sleep(.001)
 window.after(18, update)

# Starte den Fenstermanager
window = tk.Tk()
window.title(str('Fenstername'))
window.geometry('400x130')

oled_a = tk.Label(text = '', font=("Ubuntu Thin", 10))
oled_a.pack()
oled_b = tk.Label(text = '', font=("Ubuntu Thin", 10))
oled_b.pack()
oled_c = tk.Label(text = '', font=("Ubuntu Thin", 10))
oled_c.pack()
oled_d = tk.Label(text = '', font=("Ubuntu Thin", 10))
oled_d.pack()
oled_e = tk.Label(text = '', font=("Ubuntu Thin", 10))
oled_e.pack()
oled_f = tk.Label(text = '', font=("Ubuntu Thin", 10))
oled_f.pack()

window.after(18, update)
window.mainloop()

hmm ich weiß nicht zu 100% ob das mit dem Threading klappt, halt ob die Terminierung ganz genau so klappt halt wie du es dir vorstellst, denn feinjustieren des Skripts musst du am Ende eh selber machen

, aber probier es mal so aus:

Code:

#!/usr/bin/python
import tkinter as tk
import alsaaudio
import audioop
import serial
import time
import threading
import wave
import pyaudio

# COM Port
com = '/dev/ttyUSB1'

dbm = 0
# Sendeverzoegerung
svz = 3
# PTT nach Level halten
lvl = 100
# Sende und Empfangslevel
rx = 0
tx = 0

ser = serial.Serial(str(com), baudrate=9600, timeout=3.0)

audio.setrate(8000)

# Pfad zur Audio-Datei
audio_file_path = 'path/to/your/audio/file.wav'  # Ersetze durch den tatsächlichen Dateipfad

def play_audio():
    chunk = 1024

    # Öffne die Audiodatei
    audio_file = wave.open(audio_file_path, 'rb')

    # Initialisiere den PyAudio-Stream
    audio_player = pyaudio.PyAudio()
    stream = audio_player.open(
        format=audio_player.get_format_from_width(audio_file.getsampwidth()),

        rate=audio_file.getframerate(),
        output=True
    )

    # Lese die Audiodaten und spiele sie ab
    data = audio_file.readframes(chunk)
    while data:
        stream.write(data)
        data = audio_file.readframes(chunk)

    # Beende den Stream und die Audio-Wiedergabe
    stream.stop_stream()
    stream.close()
    audio_player.terminate()

Guten morgen,
vielen dank für dein Denkansatz, aber ich würde das gerne nach einer bestimmten Zeit aussenden wollen. Er soll die Aussendung der WAV Datei erst nach 15 Minuten starten, wenn zuvor kein Audiosignal festgestellt wurde. Wie realisiere ich das?

ColdGlow · 6. Juni 2023

ja ok das ist eher einfach, da muss du die time biblithek in die update funktion implementieren

(Beispiel anhand des geänderten Codes und zudem einbisschen die Variablen-Def. verschoben in einen einheitlicheren Platz.. )

Es scheint so als könne er die Ausgabequelle nicht ansteuern bzw. finden. Kann man diese zuvor definieren?

ColdGlow · 6. Juni 2023

ja welches python benutzt du denn eigentlich? Es könnte sein, dass du ein zu neues Python benutzt und der Python Core meldet, dass du deprecated Funktionen nutzt weil die ersteller der Libs halt nicht so schnell hinterherkommen beim Code-Refactoring weißt du, deswegen ist es wichtig zu wissen welche Version man für sein Projekt (für den jetzigen Augenblick halt) am besten benutzt

Python 3.11 ist halt schneller und effizienter gemacht worden, aber da wurde soviel abgeändert, dass alles refactored werden muss.

Python 3.9 hat zur Zeit die meiste Verfügbarkeit was auch den Support der Libraries angeht afaik

Zudem kann er keine richtige Konfiguration finden und einstellen weil dein ALSA und JACK-Server nicht richtig konfiguriert sind oder deprecated sind, aber ist nur die Log, man muss die Log auch anhand der spezifischen Python Version betrachten etc.

Derzeit nutze ich Python 3.10.6. Die Funktionen habe ich ersetzt gegen:

Python:

audio = alsaaudio.PCM(alsaaudio.PCM_PLAYBACK, alsaaudio.PCM_NORMAL,
    channels = 2,
    rate = 8000,
    format = alsaaudio.PCM_FORMAT_S16_LE,
    periodsize = 160)

und das Problem mit den "Warnungen" sind nun weg. Jedoch meckert er nach wie vor das er den Audioausgang nicht nutzen/finden kann.

Exception in Tkinter callback

Edit: Fehler behoben. War eine falsche Definition. Jedoch sagt er beim absspielen folgendes:
