For example, instead of choosing OGG or WAV, you can pick the actual device, like Sony, Apple, Nokia, Philips, Microsoft, HTC, and others. Output Formats: AAC, AC3, AIFF, AMR, FLAC, MP3, MP2, OGG, RM, WAV, and WMAĪfter importing files to convert, this program lets you choose any of the output formats from above or pick from a device if you're not sure what format the file needs to be in.Input Formats: AAC, AC3, AIFF, AMR, FLAC, MP2, MP3, OGG, RM, VOC, WAV, and WMA.Not only can it convert multiple audio files in bulk, but it can merge the files into one, much like Freemake Audio Converter. Hamster is a free audio converter that installs quickly, has a minimal interface, and isn't hard to use. AUDIO COMPRESSOR FREE DOWNLOAD FULL VERSION SOFTWARE WINDOWSOfficially supports up to only Windows 7.ĭoesn't let you save a default location for converted files you're asked each time you convert something. Windows 11, 10, 8, and 7 are supported, as well as macOS 12 through 10.12. If you want more advanced options, this program lets you customize things like the default output folder, whether you want to automatically add the converted songs to iTunes, and if you want to search online for cover art, among other options.įortunately, these settings are hidden away and are completely unobtrusive unless you want to use them.

The building project is usually built in a densely built area. The area is excavated downwards to tens of meters deep, thus contractors deal with several types of soil. Earthwork of building projects have distinct characteristics. This paper presents an application study on the UAV-based earthwork monitoring of a high-rise building project in the Republic of Korea. Earthwork monitoring is essential to complete the earthwork on time, according to plan, and within budget. One of the construction works that can be monitored using UAV is earthwork. Compared with traditional methods, UAVs collect data faster and more efficiently at a lower cost. Unmanned aerial vehicle (UAV) is one of the most prominent technologies in the construction industry for data collection purposes. #Superior conveyor stockpile calculator software#The computations of the volumes were carried out using two software and comparisons were made both with reference to the different survey configurations and to the computation software. The test was carried out with two UAV flight sessions, with vertical and oblique camera configurations, and using a terrestrial laser scanner for measuring the ground control points and as ground truth for testing the two survey configurations. This study shows the results of a test for the monitoring and computing of stockpile volumes of material coming from the differentiated waste collection inserted in the recycling chain, performed by means of an unmanned aerial vehicle (UAV) photogrammetric survey and the generation of 3D models starting from point clouds. Last-generation 3D data management software allow for the processing of increasingly truer high-resolution 3D models. Over time, the monitoring techniques have undergone an evolution linked to the progress of measure and data processing techniques starting from classic topography to global navigation satellite system (GNSS) technologies up to the current survey systems like laser scanner and close-range photogrammetry. The monitoring and metric assessment of piles of natural or man-made materials plays a fundamental role in the production and management processes of multiple activities. The study case was performed as a part of a master thesis. On the other hand, UAV photogrammetry presents a fast, accurate method for mapping large areas and calculating stockpiles volumes. On one hand, extremely precise measurements could be performed by GNSS technologies, however, it could be really time consuming. Often legislations concerning mine engineering state that the volumetric calculations are to present ☓% accuracy of the whole amount. In other words, this means getting an objective evaluations of the processes, using up-to-date technologies and reliable accuracy of the results. Fast and precise acquisition of measurements regarding the process taking place in a quarry is the key to an effective and stable maintenance. For instance, the management of an open pit quarry requires gaining, processing and storing a large amount of information which is constantly changing with time. Having considered how dynamic our world is, new techniques and methods should be presented in numerous fields. Secondly, the area of the whole quarry including the stockpile site was mapped by a UAV flight. Firstly, a stockpile was measured by GNSS technologies and later other terrestrial GNSS measurements for modelling the berms of the quarry were taken. For this purpose, an appropriate open pit quarry has been chosen. The following paper aims to test and evaluate the accuracy of UAV data for volumetric measurements to the conventional GNSS techniques. |
