The discussion revolves around the process of storing an audio voltage signal obtained from an oscilloscope in a .csv format and the subsequent recovery of that signal into an audio format suitable for playback through a loudspeaker. Participants explore various methods and tools for converting the stored data back into an audio signal.
Participants express differing views on the effectiveness of various conversion methods and tools, with no consensus reached on the best approach to recover the audio signal from .csv format. Confusion persists regarding the nature of the output from the conversion process.
Participants mention limitations related to the conversion process, including potential misunderstandings of the conversion tools and the formats available for saving data from oscilloscopes. There is also uncertainty about the specific requirements for successful conversion and playback.
Cool. I didn't know that.anorlunda said:There are many file format converters that can change your data from CSV format to WAV or MP3
I have converted a .csv document into .mp3, however, it just plays the name of every number in the .csv. For example, a number "1000" will be heard in a voice of "one hundred". It can't identify which is the time and which is the amplitude of the waveform.anorlunda said:There are many file format converters that can change your data from CSV format to WAV or MP3 or others. Then you can use any music player on the converted file.
Here is one such program. http://www.online-convert.com/file-type
What are the other formats it can save to? One of them may be more amenable.Tspirit said:an audio voltage signal can be obtained and saved as .csv (or other formats) by oscilloscope.
It can also save to binary format (.bin), or some figure formats such as .bmp, .png. I will try later.NascentOxygen said:What are the other formats it can save to? One of them may be more amenable.

I uploaded my csv file into the website "http://audio.online-convert.com/convert-to-mp3", converted it into mp3 online and downloaded the mp3 file and played it with windows media. By comparing the contents of sound with the original csv file (opened by office Excel), I found they are the same. I mean the voice is not a sound wave varying with the time (I saved a sound wave into a csv file using oscilloscope), but the data itself.anorlunda said:That sounds very strange. How exactly did you convert it?
Edit: An how exactly did you play it to listen?

Have you ever succeeded in converting a csv file into an audio file with that website?anorlunda said:It seems that you got a text-to-speech conversion instead of a file format conversion. You should try again, paying close attention to options and the small print on the Web page. Or try another conversion site such as the one I linked in #5.
I am willing to help you, but I have no sample file. I'll send you my email address by personal message, lookin your INBOX on PF.Tspirit said:Have you ever succeeded in converting a csv file into an audio file with that website?
That i have been search on Google, it it works with Android ,Tspirit said:I uploaded my csv file into the website "http://www.android-rescuer.com/recover-data-from-android-internal-memory.html", converted it into mp3 online and downloaded the mp3 file and played it with windows media.
