Yes! It should be proportional. <div class="gmail_quote">2011/5/18 Andrea König <<a href="mailto:andrea.koenig@gmatic.de">andrea.koenig@gmatic.de</a>> <blockquote class="gmail_quote" style="margin: 0pt 0pt 0pt 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;"> <div bgcolor="#ffffff"> Hi Praveen, many thanks for your reply. Is there a proportional behaviour? Means a num-buffers=150 ends in a timestamp of about 3s than a 15s long signal can be calculated by the ration 150num-buffers/3s?

To confirm your data you can run audiotestsrc num-buffers=150 ! fakesink -v and observe the last timestamp. by seeing this timestamp you can calculate the num-buffers to adjust to 15 seconds.

The element audiotestsrc has the property num-buffers. If I set the property to a defined value the signal gets an EOS. Set the property to num-buffers=150 the signal has length of about 9s. Is this the right way to calculate the length of the signal by number of num-buffers or is there another possibility? -- Best regards Andrea König (Development) G.punkt - medical services Ihre Wünsche sind unser Konzept Halberstädter Str. 115 A 39112 Magdeburg fon: +49 391 280380 fax: +49 391 2803822 mail: <a href="mailto:Andrea.Koenig@gmatic.de" target="_blank">Andrea.Koenig@gmatic.de</a> inet: <a href="http://www.gmatic.de" target="_blank">www.gmatic.de</a> Institutskennzeichen: IK331530332, OID: 1.2.276.0.76.3.1.51; (c) 2011 by G.punkt; G.punkt ist Trust center zertifiziert für elektronischen Datenaustausch mit Leistungserbringern; GF: Tino Graßhof; ST-ID: DE210661356; Nr.: 101-225-04463; Großhandelserlaubnis nach § 52a Arzneimittelgesetz; G.punkt ist Mitglied im N.I.R.
