This gig includes any of the mentioned processing of audio files plus trimming the recording and export to WAV, MP3 or FLAC format.
I have several professional tools at my disposal, from Audacity to Steinberg Wavelab, Waves and iZotope plug-ins.
One gig is suitable for audio recordings up to 5 minutes long.
In case that recording is longer, it wold be necessary to purchase additional gigs, but please note that discount is applied for each recording longer than 10mins! (check the gig extras)
Before ordering please describe desired editing/processing details so I could confirm that I'll be able to do it.
