حذف سکوت های بین مصاحبه - حذف سکوت های صدا - حذف سکوتهای یک مصاحبه !!!
بالاخره جوابم رو پیدا کردم.خیلی ساده تر از اونی بود که فکر می کردم.برای حذف سکوت های مابین یک فایل صوتی مانند یک مصاحبه و یا یک صدای ضبط شده باید چه کار کرد؟ با این روش مدت زمان فایل تقریبا 35 تا 50 درصد کوتاه تر می شود و این یعنی صرفه جویی در زمان! این یعنی شما در مدت زمان کمتری به یک سخنرانی،یک مصاحبه و یا صدای ضبط شده ی استاد خود گوش می دهید...خیلی به درد به خور هست.البته هرگز نمی توان تاثیر سکوت های به جا را در هنگام صحبت کردن،برای انتقال بهتر مطلب را نادیده گرفت.
با استفاده از برنامه ی آدوب آدوشنAdobe Audition می توان خیلی خیلی ساده این کار را انجام داد.
کافیست که مسیر زیر را طی کنید:
Choose Edit > Delete Silence.
توضیحات بیشتر را عینا از سایتی که جوابم را در آن پیدا کردم نقل می کنم:
Delete silence
The Delete Silence command detects and removes silence between words or other audio. It’s ideal for cleaning up voice prompts and speeding up narratives without affecting the foreground audio.
1.If you want to delete silence from part of a waveform, select the desired range of audio data. If you don’t select a range, Adobe Audition deletes silence from the entire waveform.
2.Choose Edit > Delete Silence.
3.Set the following options as desired, and click OK:
“Silence” Is Defined AsDetermines what Adobe Audition considers silence. In the Signal Is Below text box, enter the amplitude value (in decibels) you want Adobe Audition to consider as the maximum level for silence. In the For More Than text box, enter the duration (in milliseconds) of this maximum amplitude value.
For very quiet, low‑noise‑floor audio, enter a lower amplitude value (such as –60 dB). For noisier audio, you might enter a higher value (such as –30 dB). Enter a longer duration to keep groups of words together, for example.
“Audio” Is Defined AsDetermines what Adobe Audition considers audio. In the Signal Is Above text box, enter the amplitude value (in decibels) you want Adobe Audition to consider as the minimum level for audio. In the For More Than text box, enter the duration (in milliseconds) of this minimum amplitude value.
Enter a higher duration to ignore short periods of undesired audio (like clicks, static, or other noise). However, if the value is too high (above 200 milliseconds), short words might be skipped.
Find LevelsScans the waveform (or selected range) to have Adobe Audition automatically determine a good starting point for signal levels. Suggested values appear in the appropriate text boxes.
If these values don’t do the job—for example, words or phrases are chopped off—lower the signal level values. Increase the signal level values if not enough silence is removed.
Mark Deletions In Marker List Adds each location where silence is removed to the marker list.
Limit Continuous Silence ToSpecifies the minimum amount of silence (in milliseconds) to keep at all times. Silent ranges shorter than this length aren’t removed; silent ranges greater than this length are shortened so that exactly the specified amount of silence remains. Set this value to zero to remove as much silence as possible.
When shortening speech segments, use a setting of 150 milliseconds or so to leave a more realistic, natural sounding pause. Higher values can lead to an artificial sounding pause.
Scan For Silence NowPreviews the silence to be removed. This option reports how much silence will be removed and how many sections of silence were found. This option doesn’t actually remove silence, but it gives you an idea of what to expect with the current settings when you actually choose the Delete Silence command.
If you have an audio presentation that consists of many cuts separated by silence (such as a reel of several jingles), choose Edit > Delete Silence to make sure that the duration of silence between each cut is the same. For example, if the difference between cuts 1 and 2 is 3.2 seconds, the difference between cuts 2 and 3 is 4.1 seconds, and the difference between cuts 3 and 4 is 3.7 seconds, you can use Delete Silence to make the silence duration between all four cuts exactly 3 seconds
